The first game I suggest to anybody is Baldur's gate Dark Alliance. It's a great action RPG (though it has little similarity to BG on the PC) It's got excellent graphics, great gameplay, and a great 2 player cooperative mode.
Based on your likes, there hasn't been too much around lately, but Kingdom Hearts (Disney and Square) RPG is coming in a month and a half. Tekken 4 comes out next month as well.
If you really need a fix, Tony Hawk 3 is great, Devil May Cry, Ico (only if you are patient and can enjoy a platform/puzzle solver), Wipeout Fusion, Virtua Fighter 4 (for some, not for everyone), Twisted Metal Black (TMB
nline comes out soon)
There's lot's of games, but in a month a slew of new ones is coming thanks to the upcoming holiday season (which they start releasing games for in mid September.) I'd hold off, and get something new next month.
