I purchased Fallout 3 Game of the Year Edition and started off by installing Disc 1. Played that for a while and thought I'd check out Disc 2, which appears to contain the add-on levels. It installed successfully but I do not see any change at all to the game when I play it. Should I see something different or does it simply expand the game to include different story lines or places that I might not have discovered yet?
Thanks..
