Battle systems that display action on the top screen and data on the bottom, or which distribute either of those across both screens, will render that game borderline unusable without exception.

Gave up right at the start after being plopped into a sky palace and instructed to speak to the headmaster. Never found him/her. Instead talked to a bunch of the same NPC copy pasted throughout the place offering only ludicrously frivolous dialogue (such as "this is a dead end") and going back and forth across the terrible map comprised of artitrary deviations and locked doors.
