Awesome device controlled by a foolish company. I loved the Dreamcast. It was the first system that really made an impact in console emulation and I know I burnt a ton of CDs so I could play emulators and whatnot on there. I remember playing FF7 on there even using Bleemcast. Fun stuff. Soul Calibur took half my life away though, so much that even today, I can play the original and still smash pretty much anyone even being years out of practice. After having played all the titles, I still find the original (barring Soul Edge) to play the fastest - think the difference between Street Fighter II and Marvel vs. Capcom.
Bar none it had the most innovative titles. For the longest time I hated the PS2 (even though I owned one as well) solely because of it's fanboys who wouldn't even give the Dreamcast a chance. ESPECIALLY after it died and they'd play it and be like "Hey this is kinda cool!"
The Dreamcast also gains the most improvement out of any 3D system when played on a PC emulator, hands down. NullDC + ENB Series + Soul Calibur = epic win.
We can all thank Sega for being morons and letting such a cool thing die out.
