John Carmack talks about the DreamCast system and porting Quake3 to the system on SegaNet. It seems like it has been a bit of a turbulent ride and currently Carmack just doesnt know what the deal was. Apparently they were on the virge of striking a deal, here's a bit of it: Thanks Blue

So then more months pass and then they're all hot again to get Q3A as a modem pack-in on the DC, which I would love to do. A console game with a fixed function network interface moving Q3A with really good modem level networking and everything would be great. You'd get better performance modem-wise on the DC, mainly because you wouldn't have a bunch of other operating systems fighting for space and interfering with the network capabilities of the system. I still think it's a good idea, and they basically had a deal on the table which we were ready to sign and they mysteriously pulled out at the last minute, perhaps because they lost a quarter of a billion dollars last quarter and they just didn't have any money. I don't really know.
