Interesting! How about an alien race set on destroying or enslaving the human race has a mothership in orbit around the earth, except there is a single misfit among their ranks: the player.
So you'll have to stop the alien invasion by using both alien technology and human items (maybe humans that they abducted, too?) to thwart their evil plans! For example, you manage to stop some of the invasion force, so that only 20% of the human populace gets enslaved. I think seeing it from the alien's point of view can be quite refreshing in terms of the overall theme of the game, as well as game progression! Can't wait to see what you've planned man!
Me and the rest of NG will be waiting!
