Right now admin are going "OH GOD NO NOT AGAIN"
But actually, I was thinking of how it could tie in to existing systems rather than drafting a whole new hand to hand combat skill system from scratch.
Right now, AFAIK, the way it works is you have Brawling and Martial Arts, which are functionally similar except for the stats they're based off of.
I don't see any reason to change that, but I was thinking it would be pretty nifty to allow someone to use the Specialization system to specialize in either of these and have this be the equivalent of "selecting" a martial art.
People with Brawling could have access to one set of fighting systems (boxing, pankration, systema, etc) while those with MA would have access to different ones (jeet kune do, ninjutsu, and so on). Based on which they pick, they would receive defensive and offensive bonuses/penalties, speed penalties/bonuses, parrying penalties/bonuses, disarm penalties/bonuses and so on depending on which they had selected.
Of course, the attacks would have to be rewritten for each fighting system and this would take fucking forever. So why not have players do it? Pass out a template and of what needs to be written for each attack message and let us volunteer to fill it out. When an admin has time to go over it to make sure it isn't fucking retarded, it could just be pasted in with VMOO.
