In my opinion, Fallout 3 wasn't a bad game, it only had really bad main story and pretty bad quests. You leave the vault to find your father, you find him, father dies, water is clear and NO ONE in the entire world even gives a damn. And you're called a [censored] kid the entire game, you have the best armor, a large gun in your hands..but you're just that 19 year old kid from the vault...which svcks. Who wants to be some kid? No one.
On the other hand, even though I hated the story and lots of quests..I still had a lot of fun with the game. If Bethesda actually hires someone who can make interesting stories and quests this game might be really nice.
Or maybe they will let Obsidian create the real Fallout game once again...oh man that would be awesome.
