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 one notable time I can think of a game trying the dual perspective thing with the gamepad was Star Fox Zero at the end of its life cycle, and it was not received well at all because it made the control and aiming way too complicated since it was too much of a challenge to try to look at both screens at the same time. Can’t think of another game that tried something like that, but I did see a good number of games that used the gamepad for inventory, like the Zelda games and Monster Hunter.
