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.
The Sega Mega CD and the 32x were genuinely great pieces of hardware…but nearly all the games were awful. I love the Mega CD in particular, and I say that as a Nintendo kid.
Lunar 1&2 were originally released on the Sega CD, as was shining force CD.
There were a few decent games on it, but agreed, not many.
