i don't know if you have plans for the underground fight club yet but I wondered if, rather than linking it purely to stats, it could be more of a rock-paper-scissors affair. Put yourself, a companion, or maybe slave in the tournament. Win 3 round for the fight and move on to the next opponent. Win 3 fights and you are up against the title holder for that level. Depending who is fighting, yourself for bets or prize money, companion or slave are taken as the prize. Swapping out Rock Paper Scissors for moves more akin to Ultimate surrender and catfighting cutpunt-facesit-fingering or the likes could be fun. It could still be linked to stamina and strength with regards to how much damage a move does, so some one with high stamina may survive several more bad hands than their opponent. Plenty of scope for it to be F/F or F/M or M/M although its starting to look like a game all of its own Underground Apocalyptic XXX Wrestling UAXXXW
