No. GTA4 was a great game, no doubt about that, but it's also pretty much the most overrated game ever (among reviewers, most gamers I know feel it's overrated).
Personally, I think were I to rate GTA4, I'd have given it an 88%.
As for 2008 GotY, probably LBP. OTOH, I'm rather biased toward platformers, and 2D in particular. I haven't played Fallout 3 though, so I can't say an opinion on it (I'll get to it... Eventually)
