Somebody recommended Dynamite Cop. That person is not your friend. Try Zombie Revenge instead. In fact, look at my Dreamcast collection and get everything I rated 8/10 or higher.
Problem with getting a DC now is that all of the good games got ported to the PS2, Gamecube, PSP, or Xbox. You have the best console on the market from 1999- Nov. 2001......but you're in for some serious disappointment in 2010. Games I recommend and feel are still worth owning a DC for:
- Jet Grind Radio
- RE: Code Veronica
- Grandia 2
- Virtua Tennis
- Shenmue (for historical purposes--it's not too impressive anymore)
- Zombie Revenge
- Metropolis Street Racer
- Ecco the frustratingly hard Dolphin
- Seaman (for historical purposes)
- Any 2D fighters
- Outtrigger (if you have friend to play with)
- Spider-Man
- Quake 3 Arena
- Crazy Taxi (the way it was meant to be played)
