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.
