Walk around, shooting nerf darts at each other. It would be very balanced since each weapon would do 0 to -5 damage a shot and would be rated E because there is no violence, only teaching people how to love and tolerate.
Not to mention at half-time an episode of My Little Pony (the 80's kind of course, not the fun 10's version) would be shown to encourage even more love and toleration.
I think we have a plan here. I expect a beta by tomorrow and full launch by Friday.
