the uncharteds, the god of wars (gow1&2 hd remix was awesome) and metal gears are the obvious ones, and for good reason.
but don't miss the less-obvious-but-every-bit-as-worthy:
both little big planets are MUST haves. perfect gameplay, design and community aspects. and just effin' adorable.
all 3 ratchet and clank games for ps3 have been as amazing as playing a pixar movie. fer reals.
mod-nation racers takes the community aspect of little big planet to new heights, and lays it on top of the best mario-kart style game you'll ever play. for the 40 bucks or less it costs nowadays you get a couple of dozen pretty amazing courses and cars and as a bonus you get literally MILLIONS of user-created tracks, cars and drivers. it's pure crack. there's over a million online tracks alone. if you figure only 20% are amazing, that's a game with TWOHUNDREDFUCKINGTHOUSANDAMAZINGLEVELS. and if that ain't worth 40 bones, i don't know what is. . .
flow and flower are amazing downloadable zen-games. don't miss these.
the motorstorm games are beautiful, arcadey racing adrenalin. diamonds lost in the pile of amazing games.
katamari forever. 'nuff said.
and later this year?
a new SSX game that's looking better every week, and even better . . .
TWISTED F*CKIN' METAL!!!!
