PC Gamer is just one of several game news outlets reporting rumors that Sega is going to manufacture a PCI card that will allow people to play Dreamcast games on their computers. A lot of people think this rumor almost has to be false since the Dreamcast uses a proprietary optical disc format (although the copy protection on it was hacked awhile ago).
Here’s why I think the rumors are probably true: this would be an incredibly stupid move by a company, Sega, that has a long history of making incredibly stupid moves. Oh yeah, I would want to buy a Dreamcast PCI card so I could play the Dreamcast port of Unreal: Tournament rather than the PC version. Or maybe PC gamers are dying to ditch The Sims to play Seaman? Such a move would be crazy given that the console and PC games really service different markets — which is precisely why I would bet anything the folks at Sega are seriously considering it (btw, I’m not a PC snob and own several console systems; it’s just that the console is very good at what it does and PC games are good at what they do, and the result is usually a waste of time and money when companies try to bridge the two).
