how about make the ball cause pain while you hold it.
like 25. so holding the ball is a hazord better pass it quick!
heres another one
wallyball mode:
a volume would need to be coded that makes the ball 'armed' so to speak. so you'd place this volume along a wall or ceiling. now the ball is shot, volled, or bounced into the volume when it hits the volume the ball can then score unless it is caught, bounced, vollyed. in which it becomes disarmed untill it hits the volume again.
Right squash is smart, we in the netherlands have something called "ezelen" basicly its a game you can play with how many players you would like.. like this
player 1 : RaGe
player 2: Silver
player 3: Inphidel
Now its my turn and i shoot the ball at the wall, after that Silver has to catch it before it bounces 2 times and volleys it back at the wall, then its Inphidels turn, everytime it bounces to many times at your turn you get a letter, U start with "E", then ofcourse Z,E,L,E,N
So when you finally got the word EZELEN, you lost...
