Best Graphics/Style- Ratchet and Clank Future: Tools of Destruction
Best Sound- Call of Duty 4
Best Music- Guitar Hero 3
Best Replay Value- Rock Band
Best Story- Elder Scrolls IV: Oblivion "Game of the Year" Edition
Best Multiplayer game- Rock Band
Most Innovative Feature- Remote play with PSP, including playing Lair on my PSP with seemingly no lag
Most Innovative Game- Eye of Judgement
Best New Franchise- Uncharted: Drake's Fortune (but only because Rock band is the true sequel to Guitar Hero 2, heh)
Sleeper Hit of the Year- Super Stardust HD (my icon has my PSN ID, so add me and beat my score!)
Best Shooter- Call of Duty 4
Best Racing Game- Motorstorm
Best RPG- Elder Scrolls IV: Oblivion "Game of the Year" Edition
Best Action Game- Warhawk
Best Adventure Game- Ratchet and Clank Future: Tools of Destruction
Best Playstation Network Game- Super Stardust HD, but there are so many good ones. This is the most under-rated part of the PS3.
Game of the Year- Call of Duty 4, but only because Ratchet doesn't have multi-player. Both great games, and I might change my vote when I play Uncharted more. Also, I think Rock Band could be the game of the decade but it hasn't reached its potential yet with DLC.
Letdown of the Year- Lair, because at least I can play the PS2 version of NCAA Football 2008 (thanks again, EA...)
