John Carmack Talks Q3A Dreamcast on SegaNet has some excerpts from a recent Gamer's Republic interview with John Carmack where the id programmer discusses the Sega Dreamcast. Thanks Matthew Rorie. Among other things, the Q&A discusses the odd history of plans for a Q3A port for the Dreamcast, which is not on the boards, in spite of Carmack's enthusiasm:

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.
