I've had a look around the forum and i couldn't find a thread about Fallout 4 so here it goes.
According to this IGN article it's likely that the game will be set in Boston. Apparently Bethesda has been researching Boston and they have a strong connection to MIT. Plus, there is a reference in Fallout 3 about the Commonwealth and the Railroad the two factions in Boston.
So what's everyone's oppinion on this? What are your expectations?
