Alright, they're pretty much right across the board.
A few things I disagree with:
-BioShock should be best shooter, but it's close
-GTA4: Voice Acting and Story? WTF? Hello, MGS4's right over there...
-PSN game should be WipEout HD or Bionic Commando Rearmed.
But I'm surprised. IGN did a really great job!
