What's so great about Dreamcast?
Technically, Dreamcast is almost on par with the three current consoles. It had fantastic support from Capcom. It is CHEAP now. It has lots of great games get it for the games if not anything else, here's my collection so far if you want recommendations:
Crazy Taxi, Crazy Taxi 2, Dead or Alive 2, Grandia II, Gunbird 2, House of the Dead 2, Jet Grind Radio, JoJo's Bizarre Adventure, King of Fighters Dream Match 1999, King of Fighters Evolution, Phantasy Star Online, Resident Evil 2, Resident Evil 3: Nemesis, Sega Smash Pack Vol. 1, Shenmue, Shenmue II, Skies of Arcadia, Sonic Adventure, Sonic Adventure 2, Soul Calibur, Street Fighter Alpha 3, Tony Hawk's Pro Skater 2, Typing of the Dead, Virtua Fighter 3tb, Zombie Revenge.
And I still have about 50 games on my to get list.
Bad things?
-Akward controller, for me I can never really hold it comfortably, and the analog stick is always slipping out of my hand.
-The memory cards don't hold much, and if you get an 8x card you have to change between 4 200 block sectors.
