I want to make an RPG with a reverse XP mechanic. You start the game at level 99 and a full suite of skills, and they disappear as you progress. You fight the final boss with nothing but a few HP, your wits, and a wooden sword.
So at the start of the game, when you're new, your battles are about choosing optimally between 20 different powers. And at the end, with maximum experience, the battle is about pressing "sword attack" repeatedly until the enemy dies.
