Yes, "sims" battle, which means that you have to battle with characters that have absolutely no special powers whatsoever. It takes place in your crazy aunt's mansion- you know, the one with all the victorian furniture, polished silverware, tons of fireplaces and very expensive lamps precariously placed throughout the rooms. I'll be the crack using, high school dropout with a black hoodie and skateboard. You can be whatever (sim) you want.
Challengers?
Skateboarders don't smoke crack.
AFAIK.
Let me know if you're still up for this GM, because it sounds like fun.
