Now I see what the hype is, I friggin' love this game so far! As a big fan of RPG's my current standard for excellence for WRPG (western-RPG's) has been Fallout 3. I won't say ME2 is better yet, but the newer game engine and the Sci-Fi setting def makes it fun. ME3 is a must buy when it comes out.
With FO:New Vegas basically being a rehash of FO3's engine I'll still be getting the GotY edition but I know the tech will be a bit dated. Good thing though is Bethesda has a new game engine coming out for Oblivion V which I'm sure will make its way to the next FO game.
I'll probably be getting the GotY of the new Oblivion V but I still haven't touched the GotY of Dragon Age Origin's yet, haha.
