lol, just saw that thread. I was actually trying to make some kind of sumo mod today as well, I made it with a lighter gravity (-27.00), and tf goes 5*30,5*40,5*50 and dojo is 300 (gravity is lighter).
I'll give yours a try
@Meow, I don't think the appelation "sumo" means it has to be somewhat realistic with the proportion of the dojo and all, just like aikido.tbm has nothing to do with real life aikido. It's the principle of the mod that makes it "sumo", trying to push the other guy out or dq him.
