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.
Atari Lynx. Remarkably powerful handheld for coming out two months after the Game Boy, but no truly memorable games that aren’t ports (which could be said about all of Atari’s non-2600 consoles tbf.)
Atari Jaguar just had Amiga/ST ports, hardly any used the GPU.
Also, most PS5 games are just reconfigured PS4 games.
