it's a long shot, but i think it just might work...with ~10 people of course
heres how it works:
1 one person is "it"
2 they must shoot a projectile of some sort (Gun)
3 the said projectile has to hit someone in order for the target to be "it"
-the person hit is now "it"
4 repeat steps 1-3 until people get bored
this can span or one system or multiple systems...
we can work out the kinks if people decide to step it up.
well whadya think?
