We need a video game, where you are a very fit man who loves exercise and healthy food and all that shit. You hate fat people though, so whenever you go outside (open world game) you have to fight through crowds of fat people to get to your destination (Like Dead Rising 2). However, you start to feel lonely and start your quest to find the last human woman on earth. You battle femayos, butterhuffers, REEEEEE'rs, hamplanets, and finally the DEATHFAT. (The only reason the deathfat is the final boss is because there is so much fat it would take many strikes to kill him.)  After many years of humans evolving into fat piles of shit, they start to evolve even further and develop striking powers. Although they have powers, you have the ultimate power, Shitlording. After you save your perfect human, that's when you get to plug in a second controller.
