I mean New york city, is too over -done its getting boring and a lot of things point to Fallout 4 being in the Commonwealth which would be awesome!
new york would be nice for a fallout game, any big city is ok with me, as long as their is a big city in the game, cities have a lot of different areas to explore and cruise around, skyscraqers, industrial areas, slums, neighborhoods, apartment complexes, parks, airports, subways, commercial areas, even in FO3 the city could of been a lot better, so i hope a large city area is in the next fallout game.
