Is there any retro consoles that you never lived up to their potential? where the games fell short of the hardware?.
Personally I feel that the NDS was under-utilized, as it was a fully 3d capable console, that was used mostly for 2d pixel art games, and platformers. When it was able to support full 3d platformers and even a fan remake of portal.
They pushed em all right. It was too many different things in too short of a period. SEGA is now a shell of its former self, mostly chucking the name on things for some cash.
