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.
Metroid Prime Hunters is a fully fledged 3d, fps and platformer type game on the nintendo DS.
Metroid Prime Hunters and Moon are both great examples of what the DS is capable of, but they both struggle to be fun as videogames because of the stylish camera controls, what I mean by under-utilized is that a significant portion of the DS library Is 2d pixel art graphics, in games that would have benefited a lot from 3d, even within the same franchise. like super princess peach having essentially GBA graphics when New Super Mario Bros had fancy rendering and 3d assets for many aspects of the game.
