The Dreamcast had CE yes, but only about 5 games actually took advantage of it, such as Namco Musuem, Midway's Arcade pack, Kiss: Psycho Circus, and two who's names elude me right now.
All other games were written directly to the hardware, not using Direct X or CE for that matter.
In the end I can say I'll either end up with a Nintendo or XBOX 2, but NEVER a Sony, I hate them more than Mircrosoft, they themselves are Mircrosoft haters who campain against the evils of Microsoft while adapting there same policys, one of them being there LIES!!!
