Ikaruga, Crazy Taxi, Soul Caliber, Skies of Arcadia, Guilty Gear X, Soul Reaver (it's better on the Dreamcast), Sonic Adventure, Ecco the Dolphin, Rayman 2 (also better on the Dreamcast), Rez, Cosmic Smash, Bangai-O, Chu Chu Rocket, Jet Grind Radio, Phantasy Star Online, Shenmue, Street Fighter Alpha 3 (and the entire Street Fighter 3 series in case that's your thing, I prefer Alpha...), Sword of the Berserk...
Chaa... good stuff. It also has RE: Code Veronica and House of the Dead, both popular games that I don't like that much.
