I would however like to make a suggestion:
Make the story Co-Operative, similar to Borderlands where a friend/or friends can join your story and help you in missions. Once a friend joins the other persons game, you can have it set so the enemies become stronger and more difficult. That would make this game last till if you ever make a RAGE 2 ;] (Crossing fingers) hahahaha.
Doing this would also draw more people in because having a great story is nice, but having a great story that you can play with your friends is even better!
I hope you will consider this.
From a very happy consumer,
