Khans: pretty good. i like how you can convince them to make drugs that aren't going to cause massive problems. i think they are actually probably one of the few factions that can ALMOST be considered major (at least in their storyline) that you can convince to follow your ways or make them change what their doing completely. A tier.
Caeser's legion: good people if you get to know em. just gotta ignore some parts. also why is the fanart for them either really serious or just makes me question people's sexuality. B tier.
NCR: fucking despise them. i know their armor and weapons look cool and all but their questline kinda sucks... and i hate it even more because when i was doing the interrogation quest in the airport, a random NCR soldier busted in and shot the guy in the face. kinda snobby too. D tier.
Raider factions across all games (minus f4 DLC): just your average raiders. love it. B tier.
Institute: yet again you have 2 options. go with the institute's plan of effectively destroying and rebuilding the commonwealth in their image, OR you can actually make them peacefully integrate with the commonwealth.
Mojave chapter BoS: not sure honestly. their questline is really annoying for the vault part but its kinda satisfying once you get power armor training. C tier.
Enclave (yeah im gonig back to f3 for this one): aint sure. honestly. but if we are tlaking about the enclave in general from f2 to f4, 8/10 faction. A tier.
Minutemen: love it. they go down whatever route you go down. they aren'st complete dickheads. they aren't completely xenophobic.they are generally like the most balanced faction in my opinion. S tier faction.
Fallout 4 BoS: eh i aint sure. i mean yeah sure its cool and all but it feels wierd whenever i think about it too much. the xenophobia part also kinda pisses me off. dont know why tho. B tier.
F3 BoS: A tier. good leaders. elder lyons is a good dude. great version of the BoS in my opinion. and they aren't completely focused on hoarding technology. i mean yeah sure they do still take it but they try to help the people of the capital wasteland.
F4 Nuka world raiders: the pack? B tier. i just like to stick em with Cito cuz animals. operators? too snobby, really annoying. massive backstabbers too. D tier. the disciples? A. tier. i dont know why i just really like the disciples.
Trappers: run of the mill raider faction jsut with better equipment. what else do you want. B tier.
Far harbor: eh. dont mind em. B tier.
Children of atom: solid B tier. weapons are cool and all. but some of their practices and stuff put me off. i like the hallucinations tho XD.
Mr. house: D tier. dont like him. at all. almost willing to put him in F tier but probably not. bit too harsh if i do that.
Yes man: fuck yeah. love it. S tier.
Omertas: GO DIE IN A DITCH YOU SHRIVELING BALD HEADED FUCKING PIECE OF SHIT I NEVER WANT TO SEE YOUR FACE ON THIS EARTH AGAIN DO YOU HEAR ME? NEVER. NEVER AGAIN. NEGATIVE F TIER.
Van graffs: B. tier. dont know. just feels like they are your average energy weapon suppliers. combat armor is pretty cool tho.
Jacobstown: (yeah i know its not really a faction, i just like it) S tier. i like the mutants. very nice.
Followers of the apocalypse: S tier. all they wanna do is help the people of the mojave.
Tell me what other factions i should include. cuz some i can't remember properly.
