hmmm shame you don't like FPS, there are basically too many of them, so bad times for you! Killzone 2 was epic.
I dunno, what kinda games you into?
Racing... motorstorm pacific rift, wipeout HD and HD fury (PSN), burnout paradise, grid etc. wouldn't bother with Gran turismo 5: prologue now unless you really want a sim right now, cause GT5 will be out first half of next year.
RPGs... valkyria chronicles, demon souls, fallout 3 (i hate it lots seem to love it), dragon age origins, folklore etc.
Bunch of others I can't even be bothered to put into categories...
Uncharted drakes fortune
Uncharted 2 (great games)
infamous
batman AA
littlebigplanet
metal gear solid 4
ratchet and clank: tools for destruction/quest for booty/crack in time
ninja gaiden sigma 1 and 2
GTA4 (not great but some like it)
assassins creed 2
mlb 09 the show (if you like baseball)
fifa 10 (football)
nhl 10 (hockey)
madden 10 (NFL)
god of war collection (HD reboot of the 2 PS2 games)
socom confrontation
warhawk (hard learning curve now)
