Fallout 3
So Fallout 3 is pretty awesome. You might see some complaints about certain aspects of the ending, which I can tell you are completely valid, but for me it doesn't take anything away from the coolness of everything that preceeds it. Walking around an incredibly real feeling post apocalyptic version of Washington D.C. might feel like it could feel a bit depressing, but it's just so pretty in it's apocalyptic-ness. It's great just walking around, listening to the radio while slaughtering raiders. (That might sound harsh, but the raiders totally deserve it).
