Actually dudes, I got a Dreamcast now. and four controllers. And four VMUs. And some games.
It is awesome.
I trust you have:
*Powerstone 2: 1 is great, too, but 2 eats it alive
*Cannon Spike: probably my favorite shooter on Dreamcast and probably one of my all-time fav shooters, period
*Jet Grind Radio: I don't care what anyone says, this one is better than the XBOX game
*Frame Gride: freaking awesome, too bad it's import-only and the load times are PS3-like (ooh, burn!) in length
*Maken X: this was long before every other console game was an FPS, and it's still actually fun (or was about three years ago)
*Shadow Man: absolutely awesome, underrated, action adventure (for good or ill, it also destroys its sequel)
*Spawn/Heavy Metal Geomatrix: I know a lot of people don't care for these, but I have a real thing for games that combine extensive melee combat w/ big guns in a competitive environment (essentially what Quake was originally going to be)
*Bangai-O: I actually like this best on N64, but the DC port is still super fun
*Under Defeat: awesome, import, shooter by G-REV
*NOT Shen Mue: I didn't care for it then, now just thinking about it makes me irate (but I'm sure you Yakuza fans just love it)
There are a lot more, but you need all of those.
