辐射世界是一个管家机器人投入应用，小型激光武器成为常态的世界。汽车看起来都像是20世纪50年代的概念车：镀铬，有着巨大的尾翼，并且由核聚变发动机提供动力。虽然有类似于台式电脑的终端机(外观与20世纪80年代商业化的台式电脑相似，图形界面原始且储存容量极小)，但计算机的体型普遍巨大，并使用磁带储存(虽然样式古老，但在某些方面比我们现代的超级计算机更加强大)。服装风格，建筑，装修和家具仍旧严重受到20世纪50年代美国文化的影响，这一时期的流行风格，如艺术装饰风格和未来主义仍然在辐射世界中有普遍体现，海报和标识也倾向20世纪50年代的风格。电台，而不是电视，仍然是最普遍的大众媒体，并且食品也是快餐时代中所普及的(如盒装芝士通心粉，肉罐头，索尔兹伯里牛肉饼等)。广播电台主要播放20世纪中叶的美国经典，如The Ink Spots，猫王和Andrew Sisters，尽管这可以解释为只有这些唱片在大战后幸存。
在辐射世界中，20世纪50年代偏执的政治观点和共产主义与资本主义两大阵营的对立，仍是北美地区人们日常生活的一部分。例如在Take it Back!任务中，自由金刚高喊的口号“Death is a preferable alternative to communism!”(比起共产主义，死亡是更好的选择！)对应50年代“Better dead than Red!”的反共口号。反共宣传在美国流行文化中似乎也有体现，如电子游戏(Red Menace，即红色威胁 等)和漫画(Commie-Kazi vs. Manta Man,即蝠鲼侠vs共产海豚)等。
Radio, rather than television, remains the most common mass media, and food products are based on those popularized in the TV-dinner era (boxed macaroni and cheese, canned meat, Salisbury Steak TV dinners, etc.). Radio stations mostly play mid-20th century American classics by The Ink Spots, Bing Crosby, or The Andrews Sisters, though this could be partially explained by the fact that only these records survived the Great War.
辐射世界与现实之间的差异最早形成的时间尚不清楚，但应该不会早于1945年——也就是第二次世界大战结束的那一年。产生差异的一个可能的原因是辐射世界里的电子设备发展水平不及现实世界——比较有力的证据是在辐射世界中，晶体管直到2023年才被发明出来，远远晚于现实世界中的1947年。这或许能够解释为什么游戏中的电脑技术为什么相对落后。事件对应的日期很难确定，因为即使在时间线分歧之后，两个时间线也并不是完全错开的。 例如，Fallout 3 中核弹镇的某些居民偶尔会说“不要让他们打着嬉皮士的幌子欺骗你”，以及 Fallout: New Vegas 隐秘山谷地堡的涂鸦包含反核，亲 “和平”口号，让人联想到60年代反主流文化所使用的口号。 虽然“嬉皮”一词早在1945年就已存在，但它直到20世纪60年代才进入主流美国词典中。很明显，类似于我们世界中嬉皮反文化的兴起也发生在辐射宇宙中，或者嬉皮士运动也可能正常发生。 Fallout 4 的开头动画也表明，对广岛和长崎的轰炸等第二次世界大战的事件以同样时间与方式发生，证明了1945年是时间线分歧前的最后时间点。
虽然辐射的时间线与我们的时间线在1945年之后的某个时间发生了重大分歧，但是在1945年之前的辐射时间线中也发生了一些与我们的时间线不同的事件。 然而，这些都不会对人类历史产生重大影响。 这些差异中最值得注意的是在地球轨道上存在一个外星宇宙飞船，以及至少1603年以来对人类进行的外星人相关的绑架和实验。其他辐射时间线独有事件的例子包括： 1918年首次制造夕阳沙士，1932年维姬和万斯的犯罪狂潮，以及Vim! 流行公司 于1931年的成立，在第二次世界大战结束的十多年前。 1943年建造的密苏里号在自由博物馆的壁画中的不同之处在于，她有4个主炮塔，而不是3个。
在时间线分歧之后美国国旗的更改，证明美国发生了巨大的变化。 在1969年，50个州被巩固（加利福尼亚则是分裂）为13个联邦，尽管看起来各州本身保留了一定程度的主权（从米歇尔医生房屋外面的内华达州旗以及各种车牌装饰上有州名而不是联邦名称可以看出 ），However, this could be seen as a way to make organizing plates a lot easier, as merging three states into commonwealths would lead to 3 duplicate plates.
时间线分歧的其中一点是战前美国的价格膨胀。 可能是因为化石燃料的稀缺，战时支出以及世界性的政权不稳定，美元在大战前的几年中经历了严重的通货膨胀。 许多东西，从汽车，汽油到玩具和食品，价格都远高于我们的世界。 值得注意的例子是：
- 像波士顿号角报和华盛顿邮报这样的报纸每期售价56美元。漫画和杂志，如Guns and Bullets(枪支和子弹,Fallout 4及Fallout: New Vegas版本在此)，Unstoppables(无人能挡)和Astoundingly Awesome Tales(惊世奇谭)，根据具体内容，价格从15美元到33美元不等。
- Chryslus Corvega于2077年上市，价格"仅"为199,999美元。
The entire reason for the Great War and the Resource Wars is the world's petroleum reserves running out by 2052 in the Fallout world. This is based on the infamous 1956 peak oil theory. Famous real-life events related to petroleum demand that parallel the events leading up to the Great War in the Fallout universe include the Yom Kippur War, during which the OPEC (Organization of the Petroleum Exporting Countries) made an embargo on oil by increasing prices by 400% and leading to the 1973 oil crisis, and the Prohibition era which outlawed alcohol at a time when it was set to replace petroleum as a fuel source for automobiles. It is unclear if there were any events behind-the-scenes pertaining to the demand of petroleum in the Fallout universe (given its uses of technology and its respective fuel resources differing from ours), but it is peculiar, given that there are pre-war energy alternatives, such as Prometheus Coal, Helios Solar, Greenway Hydroponics, Gecko's nuclear power plant, Olney Powerworks, the Hoover Dam power plants, etc. It is also unclear exactly how dire Europe's energy shortage was in 2052 which led to the European Commonwealth-Middle East War and China's energy shortage that led to the Sino-American War, as there is no mention of ulterior geopolitical motives or artificial demand anywhere in the Fallout world.
Oil still exists in Fallout 4 and Fallout 76. It is an item used in crafting meant as a "catch-all" item (meaning it could be an oil other than petroleum), but its appearance and presence in items such as the lantern, Fuel tank, and Mr. Handy fuel among others implies it is a petroleum derivative.
City design in the Fallout universe differs from that in ours, often to the point that the cities are only superficially similar in layout and presence of familiar landmarks.
Looks similar to the American capital city of our world in terms of the placement of signature buildings and overall urban design, but has some noticeable changes:
- Much of the pre-War contemporary architecture is 1940s/'50s art deco & 1950s/'60s modernist.
- The skyscrapers that define Arlington, Virginia in our reality do not exist.
- Buildings such as the Smithsonian National Air and Space Museum are replaced with the Museum of Technology. The Museum of Natural History and Museum of American History have been replaced by the Museum of History. Several Smithsonian museums also do not appear in-game.
- Busts of persons apparently famous in the Fallout world while unknown in ours are located on many buildings.
- The Capitol Building has two single flight sets of stairs on its front facade (the side facing the Mall), rather than dual sets of stairs.
- The Mall is smaller and more compressed than the real Mall (though this may just be an instance of the entire Capital Wasteland being smaller and more compressed than the real D.C. area)
- The subway network is different; there are fewer lines and the stops are different (the D.C. subway network in Fallout 3 has 3 lines, Red, White and Blue), while the real D.C. subway has 6 lines (Red, Orange, Yellow, Blue, Green, and Silver), though admittedly the Silver Line was still a plan-in-development at the time of Fallout 3's release and had not even received funding to begin its construction.
- The Washington Monument has a steel skeleton, which the real monument doesn't have.
- The Pentagon is located in a different location than our universe, being right on the banks of the Potomac next to the Arlington Memorial Bridge which in-game has been renamed to Francis Scott Key Bridge.
- An elevated monorail network ran through the city and surrounding areas. No monorail networks exist in D.C. in our timeline, though some parts of the "subway/metro" are in fact elevated above ground, for example the Red Line between Union Station and Forest Glen, or the Yellow line where it crosses the Potomac River.
- Many buildings and memorials built since the 1950s and 1960s in our timeline (such as the Vietnam War Memorial, the World War II Memorial, Nationals' Park, Korean War memorial, FDR memorial, Theodore Roosevelt memorial, the Kennedy Center, the Newseum, Etc) either were never built or were destroyed and totally forgotten.
- Union Station does not appear in-game.
- The Supreme Court building does not appear in-game.
- Factories remain fairly common, as was the case during the American industrial economy of the 1940s-1960s, and, while heavily automated with robotics, are still quite primitive by our present-day standards.
- Towering highways criss-crossed the area, in some areas standing 85-100 feet off the ground, even running through Central Boston.
- Quincy Market, which opened in 1825 opposite Faneuil Hall does not exist, and neither does the ring of stores surrounding it.
- Sanctuary Hills does not have a Minuteman Statue on the right side of the road exiting the neighborhood, but rather a completely different statue of a Minuteman in the middle of the road. The bridge used for entering and exiting Sanctuary Hills is in fact, a reality, as it does exist. The last thing is, there is no neighborhood in Sanctuary Hills, but rather an open area of land.
- Cabot House (erected 1711) was never built in our world.
- The Strip, as well as the greater remains of Las Vegas proper in the Fallout universe appear to be a lot smaller than the city in our world. A large number of Las Vegas' casinos and prominent structures also seem never to have been built, instead replaced by similar buildings or simply nonexistent.
- Nellis Air Force Base as it exists in the Fallout universe appears isolated and relatively distant from Las Vegas. However, while the location is mostly geographically accurate, the real base is surrounded by urban sprawl and far less removed from it.
- Hoover Dam is significantly shorter than its real counterpart, and also lies much closer to Las Vegas than the dam does in the real world. The exterior of the dam is mostly accurate to the real thing in appearance, but the interior diverges significantly.
- Mike O'Callaghan–Pat Tillman Memorial Bridge, which runs adjacent to Hoover Dam and carries traffic from Route 93 (which previously ran across the dam itself), does not appear to have been built. However, the bridge was only completed on October 14, 2010, mere days before Fallout: New Vegas was released.
- The B-29 Superfortress submerged at the bottom of Lake Mead, while real, is in significantly worse shape in the real world and far more corroded than it appears in Fallout: New Vegas even in the present day (let alone 200+ years in the future when 2281 comes to pass.)
- The Lighthouse that appears in-game looks very different in real life.
- In the Fallout universe John Smith discovered Point Lookout in 1612; in OTL it was in 1608. Also due to a gunpowder explosion in 1609 he had to return to England for treatment and didn't return to the Americas until 1615.
- The city still is and has grown for steel industries to the point where there are factories and steel yards in the uppertown area, in the Fallout universe. But for our timeline, in Pittsburgh, the steel industry has mostly gone out of business.
- The Pitt Bridge before the war was actually an updated version (specifically remodeled after the 10th Street bridge) of the Wabash bridge in the Fallout universe. As for our timeline, the Wabash bridge was demolished in 1948 after decades of neglect. Two piers remain in places today, the only remnants of the bridge still in place at the original site in our timeline.
- Haven, used by Ishmael Ashur as a home is the Cathedral of Learning in the middle of downtown Pittsburgh. In our reality, the Cathedral of Learning is located outside of downtown Pittsburgh on the University of Pittsburgh's main campus in the Oakland neighborhood, east of downtown.
- The Coast around Far Harbor (Bar Harbor in our world) appears to be a lot higher than in our world.
- The Cathedral is a prominent building that was built post-war and appears in the original Fallout is not in the real world.
- The character on the Camden Park sign is different than the one used in real life (which is a clown). The park is also missing a few rides/attractions as well as certain areas of the park such as the picnic shelter.
- Huntington and Wheeling don’t appear in game, whereas they are two of the largest cities in WV in real life.
- Flatwoods is much smaller featuring only a small version of the older town and much if not all of the newer areas don’t appear.
- Sutton's Dam is not featured in game.
- West Virginia University is now known as Vault-Tec University.
- The Greenbrier Resort has been renamed to the Whitespring Resort.
- Hillbilly Hotdogs has been renamed to Hillfolk Hotdogs.
- The New River Gorge Bridge appears right over Flatwoods in game where as in real life they are further away from each other.
- The Mothman statue in Point Pleasant doesn’t have arms where as it does in real life.
- The Greenbank telescope is on a hill where as in real life it’s in a large field; it has also been renamed in-game to the National Isolated Radio Array. The science center does not appear in game.
- The Summersville lighthouse is further away from the lake than it is in real life and is renamed in-game to Landview Lighthouse.
- The Tamarack does not appear in-game.
- The Pumpkin house is far to the north east in game, where as in real life it is to the south west near Kenova and Huntington.
与现实相比，辐射世界最大的区别之一在于数字计算机和电子产品没有出现小型化趋势。最突出的例子是晶体管，在现实世界中早在1947年便被发明出来，并在随后的半个世纪中掀起一场微电子革命。但在辐射世界中，晶体管直到2067年才发明，而它的后继产品——半导体微处理器芯片更是从未出现过。这直接影响了辐射世界中的数字计算机发展，在游戏中，计算机并不像现实里的那样普及，而且它们大多采用老式的磁带作为存储介质，不仅内存狭小，还需要占用大量的安放空间。辐射世界中的个人计算机虽然小很多，但同现实相比，他们依然显得很笨重，而且基本上都采用单色的阴极射线管显示器，带有一体式的键盘，外观上近似于现实中1970年代的Intertec Superbrain计算机，以及苹果公司设计师哈特穆特·艾斯林格为Apple II计算机设计的原型。不过不可否认的是，这些计算机大都十分坚实、可靠，甚至在被制造出来210年后还可以正常运作。These computers are very advanced in their processing power, indicating that progress continued in computer science (albeit at a slower rate than in our universe), but the technology to make them smaller never emerged on a large scale: technologies like the Pip-Boy and androids require miniaturized electronics to function. Nor did user-friendly icon-based graphical user interface (GUI) operating systems, which first appeared commercially in our world in the 1980s. UIs remained fairly basic command-line affairs, and less frequently advanced voice interfaces (as per computers in 1950s science fiction) were developed for computer systems which made a GUI redundant on such systems.
Television sets and radios also failed to evolve past the early 1960s level, and television in the Fallout universe remained in the same monochromatic hues as its computer screens, as well as having tiny displays and large frames. However, color television seems to not be prominent in the Fallout universe despite the fact that color television first became mainstream in 1953. Another example of technology failing to evolve can also be found in cameras. Cameras in the Fallout universe are big and bulky with large flash bulbs like those used in the late '50s and '60s. Interestingly enough, however, the CCTV cameras seen in Fallout games are just as compact as those in the real world.
Various references to uploading and downloading, as well as to e-mail and networked communications, also demonstrate that though the Fallout universe lacks our mastery of microprocessor technology, other aspects of computer science proceeded unhindered, such as robotics, the development of the Internet, and orbital communications satellites.
In the Fallout world, nuclear power was not only used for atomic bombs, it was also harnessed in nuclear reactors, which became a prominent source of energy. Large scale fission reactors that powered whole towns as in our world existed, but were a lot more common. These power plants were smaller and they often existed underneath towns and cities, such as the one in New York that almost went into meltdown and the powerworks beneath Olney. But similar to our world where more priority was put towards making electronics smaller, more priority was put towards making nuclear reactors smaller in the Fallout universe.
They were reduced in size to the extent that they could be used in roles more typically occupied by internal combustion engines in our world, such as car engines and small electrical generators, or even in fission batteries. Controlled nuclear fusion, a source of energy which is yet to be harnessed by scientists of our world, was developed. Fusion reactors were used to power vehicles and, like fission reactors, were reduced to very small sizes for use in power cells which were the standard for powering medium energy weapons in the military. Many of these pre-War power sources are still functioning around the time of Fallout 3 and Fallout: New Vegas. One example of functioning mini reactors are the ones in radios and televisions across the wasteland. It is seen in the demo video of Fallout 3, that there is a mini reactor still pumping out energy in a destroyed bus radio. This also explains the lack of power cords on the radios and televisions in the wastes.
This nuclear obsession of the Fallout world saw nuclear energy and, to a lesser extent, radioactive materials, being utilized wherever possible; even seeing radioactive isotopes added to a type of cola at one point despite the inevitable health risks of ionizing radiation. Their world's obsession with nuclear energy ultimately ended in the destruction of pre-War society.
Along with this proliferation of nuclear technologies came the risk of radiation poisoning during accidental radiation exposure. In response to this threat, radiation treatment and inoculation technologies were developed in the Fallout universe. Such technologies have yet to be realized in our timeline beyond very early experiments.
All of the Fallout games use a combination of fictional weapons and weapons similar or identical to real-world examples. The games vary in their faithfulness to canon and logic in their choices of which weapons are included as well as in how the weapons' characteristics have been modified from their real-world counterparts.
The development of nuclear weapons in the Fallout world differed from our universe in that the majority of nuclear weapons remained in aircraft-delivered bomb form, while only a minority were miniaturized into warheads and placed atop ballistic missiles. The progress of nuclear weapons apparently stayed at the atom bomb level and improving upon it; thermonuclear and hydrogen bombs were either never researched or abandoned in favor of atom bombs. There are a few examples of a nuclear missile in-game: the Minuteman ICBM in Fort Constantine. Other areas, such as Fort Bannister and the Wheaton Armory, have missile silo doors that are similar to the one found at Fort Constantine but feature no apparent way to launch missiles. This suggests that the missiles in these facilities were launched during the Great War. In The Divide, there are a large number of un-launched ICBM's, suggesting they were prepped for launch, but never got the call during the short period of mass destruction. It is suggested that nuclear-capable countries, such as the U.S. and China, had begun converting their nuclear stockpiles to ballistic missile form by the time of the Great War in 2077. Aircraft-delivered nuclear weapons took the form of the old-style bombs used in the 1940s and 1950s, similar to the Fat Man dropped on Nagasaki in World War II. Although electronic miniaturization was accomplished in the Fallout universe, nuclear bombs of the late twenty-first century still retained the Fat Man-esque shape. However, in New Vegas, Mr. House mentions having defended the city from 77 nuclear missiles, suggesting that the Chinese at least had access to substantial numbers of warheads in missile form. Also, information on the computer terminals found in the Washington, D.C. Museum of Technology would suggest that the American military recommissioned the Delta IX rockets as nuclear warhead vectors. Additionally, the "Minuteman" series of nuclear missiles (First launched in 1962 in our universe) appear to have also been developed and expanded on in the Fallout world, as "Minuteman XI" missiles appear in both Fallout 3 and Fallout: New Vegas, while the Minuteman III is the latest in our world.
Rifles retained designs of weapons that originated in the 1940s and 1950s, such as the AK47 or FN FAL. There is evidence that despite the diverging timelines, weapons development in the Fallout universe followed a similar path to ours. Picatinny rails (a technology that is only recently been implemented in our universe) as well as weapons such as pump-action grenade launchers and break-action grenade rifles, which were developed around the 1960s for the Vietnam War in our timeline. Handguns also retained similar designs to those of the early 20th century. Heavy weapons, such as missile launchers and the Fat Man, had unique designs such as side mounted foregrips and pneumatic ammunition loading systems. Weapons that seem impractical in our timeline, such as nuclear catapults and man-portable miniguns, were extensively developed in the Fallout timeline and issued to frontline troops. Ammunition calibers that are not common in our timeline, such as the 10mm, are widely used in the Fallout era, while common ammunition in our timeline, such as .50 BMG, .45 ACP, etc. is utilized for more specialized roles, such as high caliber rifles and submachine guns.
Guided missiles exist in the Fallout timeline, but are much less commonly used. As mentioned above, intercontinental ballistic missiles existed during the Great War, however, most nuclear weapons appeared to be free-fall bombs. Smaller hand-held Missile launchers capable of locking onto targets, particularly metallic targets such as robots or turrets with the Vault-Tec Assisted Targeting System also exist, possibly originally intended as anti-tank, anti-power armor, and/or anti-robot weapons. Guided missile cruisers such as the USS Ebon Atoll were also in service with the US Navy by the 2050s. In spite of the development of handheld and naval missile systems, aircraft launched air-to-air or air-to-ground missiles may not been invented until the time of the Great War, as the primary armament of Great War-era Fighter jets of the game appear to be armed only with nose-mounted machine guns, suggesting aerial warfare tactics changed little since the 1950s. Guided missile launchers have only been confirmed on the cutting-edge Vertibird VTOL aircraft.
异尘余生宇宙有三台重要的卫星轨道武器。一台代号为Highwater-Trousers（短管长裤）的轨道飞弹平台，在异尘余生3中可透过卫星站的终端机使用。一台名为Bradley-Hercules（布莱德利-海克力士）的高爆飞弹轨道平台，此武器在异尘余生3的拓展包Broken Steel中摧毁了Liberty Prime（自由至尊）。出现于异尘余生:新维加斯中，搭载雷射的Archimedes II（阿基米德二世）。他们都瞄准了地表上的某个位置，可以消灭任何威胁。游戏中的对话表明核武器与雷射武器的轨道武器网路都是存在的。
现实世界的卫星轨道武器实例是苏联的8K69部分轨道轰击系统（Fractional Orbital Bombardment System，FOBS），是将装载核子飞弹的可重返大气层载具部属在低地球轨道，可待机无限久并以前所未有的速度于全球发动袭击，类似游戏中英克雷的Bradley-Hercules平台。部分轨道轰击系统于1982年逐步淘汰，以符合现已失效的SALT II条约，该条约禁止将大规模杀伤性武器部属到地球的卫星轨道上。
The Fallout universe excelled at robotics technology, to the point that robots permeated pre-War society and served a variety of roles, both military and civilian. Robots walked family pets, retrieved groceries from the store, took care of children, impersonated famous celebrities to the joy of the public and even fought in the military. The types of robots and their physical characteristics varied, ranging from bipedal Protectrons, to tracked and hovering robots like the Robobrain and Mister Handy/Gutsy, to the enormous Liberty Prime robot designed to retake Alaska from the Chinese during the Sino-American War. Robots were often powered by fission batteries and energy cells, meaning many survived the nuclear holocaust of 2077.
Rotary craft such as helicopters do not seem to be prevalent in pre-War society, despite helipads being found on hospitals and high-rises, suggesting they were limited in numbers or only used specialized roles or no wreckage survived the Great War.
Despite the development of jet power, some civilian airliners still use propellers, as evidenced by the aircraft at Camp McCarran in New Vegas. Wrecked jetliners found at Logan International Airport in Boston have enormous frames, being almost the size of a cargo plane and have five nuclear jet engines arranged in a cluster formation on each wing, for a total of 10 engines, with passenger seating integrated into the wing.
Another technological difference between the Fallout universe and our own is the approach taken to plastic polymer use. In the Fallout universe, plastic is far less prevalent than in our own, with glass and metal alloys being the materials of choice. This is likely due to the scarcity of oil in the Fallout universe, which is essential to manufacture plastic. Syringes are glass and reusable, stimpaks come in a glass vial inside a metal casing, etc. Although water seems to come in plastic Polyethylene Terephthalate (PET or PETE) bottles, the shape and size of the bottles themselves suggest they are mainly part of laboratory equipment. Intravenous preparations like RadAway and Blood packs also comes in plastic bags. However, the American military has widely employed plastic polymers - military combat armor is made of advanced defensive polymers, as is the T-51b power armor and later power armor models in the line. In Fallout 4, plastic containers and products are more common, with examples being bottles for automotive products such as coolant and antifreeze, as well as some household products such as bread boxes and dog food bowls. In spite of this, plastics are still far less common in Fallout 4 than in real life, as seen with the prevalence of glass stimpak syringes and Nuka-Cola bottles.
Specific teams are never accurately referenced by name because that would require licensing from Major League Baseball, but there are some key divergences in the Fallout timeline to be observed. A terminal in the Boston Bugle building reveals an article that states that "it has been 159 years since this city has revealed in the joy of a World Series victory." This would mean 1918 was the last time Boston won a world series. In reality, they have since won in 2004, 2007, 2013, and 2018. (This could be a reference to the Curse of the Bambino, which in reality was broken in 2004.) The article also makes reference to ways Boston has previously lost their chance to win. The line "[lost by a] ball that rolls disastrously through an infielder's legs," is a clear reference to the nature of the error made by Boston first baseman Bill Buckner that allowed the New York Mets to win Game 6 of the 1986 World Series (and eventually the whole series) over Boston when the Red Sox were one strike away from winning the game and the championship.
The baseball cap and uniform have a red-and-white color scheme, suggesting the Red Sox departed from their traditional red and navy blue uniforms. Furthermore, batting helmets found throughout the Commonwealth are royal blue.
Diamond City, a walled city built within the confines of the Red Sox home stadium Fenway Park, features a collection of retired team numbers in the left field stands. These numbers include 1, 4, and 6, which are retired numbers in reality. Most of the remainder of the team's currently retired numbers (8, 9, 14, 26, 27, 45, and 49) are not present. Two numbers that are not retired in reality are retired in the divergent timeline: 11 and 13. Finally, there are also two numbers retired in reality that were likely retired in the Fallout universe at some point after the Divergence occurred; the numbers 21 and 33, worn in reality by Roger Clemens and Jason Varitek, respectively.
Boston's opponent in the 2077 World Series is mentioned in the game as 'Texas'. This suggests the Texas Rangers, but it makes no sense with current timeline teams because both the Rangers and the Red Sox are American League teams and would not be facing each other in the World Series. (It's possible that the opponent was meant to be the Houston Astros, but this team is commonly referred to as 'Houston' to differentiate it from the Rangers. Not only that, but the Astros are also currently an American League team, giving the same problem. This could be remedied when one considers that until 2013 the Astros were a National League team. It is also possible the divergence includes a new team being designated 'Texas' or that the Rangers moved to the National League.)
The schedule of the World Series also suggests a possible divergence from modern baseball. The fourth game of the 2077 World Series is scheduled for October 23. The length needed for the playoffs (as well as possible delays due to weather, etc.) means the first game of the World Series usually begins after October 20 and can easily continue into November before being definitively won. A World Series being resolved by October 23 is technically possible, but unlikely. A possible explanation is that there may be less than 30 teams and therefore a shorter playoff series, or that the playoffs are organized differently. It is also possible the playoffs proceeded exceptionally quickly that year.
Finally, given that the baseball card of Matt "The Missile" Murtagh includes batting statistics when he is a pitcher, it suggests that the Designated Hitter rule was never implemented in Fallout's version of the American League, or at least it was eventually rescinded before 2077. More likely this is a mistake as the stats listed on his baseball card appear more akin to a position player's than a pitcher's. (Very vaguely, as the text is so small.)
