Abilitease

Abilitease (as defined on Gamespot: the Hotspot) is in a game when you start off super powerful and then pretty quickly, the story depowers you and then you have to build yourself back up. As seen in Castlevania: SOTN, Star Wars TFU, God of War 2 & 3. Also maybe Ridge Racer, where you start as a spaceship shooting lasers at an alien fleet, and quickly devolve into a car driving kind of fast.
