Crystal City was going to appear in Fallout 3 but was cut from the final version of the game.
Behind the scenesEdit
In real life, Crystal City is located directly and shortly south of the Pentagon, easily seen on a map. It is highly plausible that Crystal City was an early version of the Mason District, since the Mason District - at least as portrayed in the game - does not exist in real life. Furthermore, the Mason District is in roughly the same location in which Crystal City seemingly would be.
