How about a game where you're a big celebrity for starring on some famous show (Star Trek, Star Wars, Twighlight comes to mind). Now you want to make your way out of the convention center you're in so you can go home and relax. Just one problem... You have to avoid the zomb... er... your fans... because if you get caught you could get ripped apart by their overzealousness....
I remember seeing a film about Bruce Springsteen literally having his clothes ripped off by his female fans as he tried to escape into his car. Not sure if it was real or not, though...
In the beginning there was nothing. There'll be nothing in the end...
