"The Dreamcast fans are very devoted. You see on eBay people are still buying the games and system," Pritchard began. "We actually have a Dreamcast collection coming out soon. We are looking to bring some of the old Dreamcast games to market digitally and packaged. The titles are still to be announced. The Ultimate Genesis Collection did huge numbers on PS3 and 360, so it's an important part of our business. We've already been releasing some Dreamcast games digitally; Crazy Taxi [for one]."
