Got a Sega Dreamcast for $25 yesterday! Its bringing back so many memories!

I am sure I have posted before in the forums about my love for the Dreamcast. I finally got one for cheap the other day. I put a few different games in and played for a little while. Even after all these years they are still alot of fun. My personal favorites are Toy Commander, Crazi Taxi 2, Sonic Adventure, Sonic Adventure 2, Skies of Arcadia, Shenmue, NFL 2k, Tokyo Extreme Racer, and others. I also have 4 demo discs that came with The Official Dreamcast magazine! Its a shame I never managed to keep those. Oh well. What are some other great games on the Dreamcast? I really want to find Jet Set Radio/Jet Grind Radio that was a very artistic game.
