I think we can just go on the honor system. I like to assume people are good rather than evil. Don't godmod, no black holes or time space bending that sort of thing. Whenever you're ready bud!
Hey Bud! I'm new here and I'd like to take you up on that offer for my first fight. I've got a tarot card-using athiest gunslinger character who might be a good match. Whadya say?
What I'm really hoping the rules are of this arena are that I can challenge someone to a fight and rank up depending on my wins. Correct me if I'm wrong. Just tell me, do I need a character sheet? Because I am so ready for a good fight.
