What was your favorite video game for the Sega Dreamcast Console?

My favorite game would have to be Shenmue...I absolutely loved that game and i had the walkthrough book for it and played it through at least 3 times. I also liked Omikron: The Nomad Soul, Rippin Riders, and of course Sonic the hedgehog. I wish i still had my dreamcast tho. What about you? Do you still have a dreamcast?
