The Devil May Cry saga is pretty entertaining though its mindless shooting and a lot of button bashing... still particularly fun and Devil May Cry 4 is coming out on PS3/Xbox360 so its obviously good enough to develop onto better consoles?
Hmm... .Hack//GU 1,2(which was boring but has good cutscenes and gameplay) and the recently released 3 Final Fantasy X,X-2(if u like X),XII Tekken 5(if you like vs mode fighting games with a good storyline) um.. maybe u can give us an idea on what types of game genres(shooting,fighting,RPG,etc) you like
I'd recommend Rogue Galaxy. Good action RPG with an insane amount of side questing to do. And they're actually fun too.
