kool kitty89: I don't agree with beefing the SegaCD as far as having limited 3D capabilities or even 32-bit CPU like SH-1. I believe in keeping the SegaCD based on sprite-scaling technology Sega used in their 80s arcade games. I beleive the Saturn should've been based around Lockheed Martin's 3D polygon texture-mapping technology, at least on par with Model 2, if not newer like the Real3D series, although not as advanced as Model 3. If the Saturn "sat" inbetween MODEL 2 and MODEL 3 technically, it could handle ports from both boards. Upgraded Model 2 games, and scaled down Model 3 games. The Dreamcast would then go well beyond Model 3, upto or even a little bit beyond Xbox1, roughly on par with a GeForce 4 or ATI Radeon 9700, easily crushing the PS2 by the same degree the more powerful Saturn would crush the PS1 & N64.
This is all fantasy, none of this happened or will ever happen. It's just FUN to speculate with what ifs.
