I'm thinking more a different style of football than the current release, the current one is based on field goal, I think it'd be cool to have Tori start with the ball and have Uke have to try and take him down, and if Tori can get the ball past a certain point it somehow activates a trigger which deals damage to uke. (I'd do this myself if I knew how to work with triggers and damage and whatnot.)
Or there's another idea - Perhaps a like.. catch mod, but the ball flies alot faster than it would from simply manually (Like joust speed) and basically it's instagib on joints so you have to try to catch it or stop it with your forearms / non-jointed areas, otherwise you're fucked. And basically you throw it back and forth..
Meh, just some ideas.
