I got my Dreamcast not on launch day, but at the Christmas right after it. It was a surprise, too, because I didn't ask for it. But I'm glad I got it because I was still reviewing games for the newspaper at the time and it really helped. The Dreamcast was my first SEGA console and really upped my respect for the company.
Some of my favorites include Sonic Adventure 1 and 2, Space Channel 5, Crazy Taxi, Samba de Amigo (still have the maraca controlellers under my bed), Marvel vs. Capcom 2, Cannon Spike, Soul Calibur, and many more!
