I come from a long history in the world of E-Feds, where players essentially write promo's, interviews, or segments as you'd see on a normal wrestling event... then based on who writes the more entertaining rp, a judge decides a winner and writes up the matches. 

The more interesting RP would involve not just the wrestlers or fighters, but the GM who makes the cards and decides the matches as well. That extra character tends to push any Organized Combat style RP a long way.
