Suggest ps2 titles

I recently bought my new ps2 slim version. I want you people to suggest some good titles in the action/adventure/fps/racing/fighting genre. I already own Need For Speed:Most Wanted, Prince Of Persia:Warrior Within and Devil May Cry: Dante's Awakening. Also what is the use of the two usb ports on the ps2 ? How much does the vertical stand for the ps2 slim cost?

Resident Evil 4 baby.This game is perhaps the most exciting game I have ever played on the PS2 and has plenty of replay value.Get God Of War,POP entire series,WWE Smackdown Here Comes the Pain(i.e if you like WWE),Tekken 5,Cold Fear,Shadow of colossus,Farenheight and the list could go on.

The USB ports are for add-on accesories like Eye Toy,A Logitech Racing wheel,Keyboard and a mouse(Though not all keyboard and mouse are compatible fully with all games).

Haven't seen a vertical stand here in Mumbai but I suggest you better stick to the normal horizontal position as that is the best.
