What kind of game has never been done before?

[Kurt Zisa]

Bad guy main character? Definitely been done. Luke Skywalker is the ultimate bad guy. He's a member of a rebel faction and succeeds in overthrowing the government.

Certainly it's all about perspective, because the bad guy is definitely the valiant hero.

If you want to look for playing the "bad guy" you'll want to decide whether it's as a rebel (good guy at heart, like a Skywalker or a Robin Hood or a Batman) or as a truly evil entity. Playing as the actual bad guy, attempting to thwart the efforts of droves of hero-types, would certainly be different. Not to say that it's never been done either, but it is a bit more of a unique idea that isn't done nearly as frequently.

I was going to suggest playing as the 'villain' aswell, or perhaps an evil organisation or something. Off the top of my head, they could overthrow/ take over the world through the course of the game and if a sequel was going to happen, a group of the people whos homeland's were destroyed could try to take it back. Although thats been done before, a lot .
