Sucks that the SEGA system missed me :/
The Dreamcast was really one of my favorite systems. I wish it had been more of a commercial success.
http://www.schtserv.com/ is the place to go if you want to play these again. They host private servers and guide you through downloading and installing Blue Burst which has Episodes 1, 2, and 4. (Episode 3 was GameCube exclusive and was basically a PSO themed card game)
Enjoy! :)
