Video Game Idea: Dimensions

The game revolves around a "protagonist" who is a fragmented being. These fragments have fallen into different dimensions and created alternative versions of the protagonist's self. However, one of the fragments held the "protagonist's" dark emotions, desires, and schemes and created an evil self. The game has the "protagonist" travel throughout the dimensions searching for his/her alternative selves to stop the evil double from controlling the multiverse.

Hahaha, sounds very interesting. But it's pretty similar to Jet Li's "The One." I'm always a fan of time/interdemensional travel. It's hard to nail down effectively, so good luck to you!
