For me, some of the best are Assassin's Creed 2, Just Cause 2 and Skyrim.
@spinningbirdcake: I can see why. Most people who played 3 never played the previous games, so to them that's what fallout is meant to be. Lots of people didn't like how NV wasn't as apocalyptic and atmospheric, but it's more of a fallout 3 than FO3. I like both games though
