Vig, I'm gonna hit you with an awful lot of questions and comments when I get a little more free time...
1. Just to clarify: adaptable martial arts can take any manuevers, ignoring the style prereqs?
2. I'm experimenting with a Bad-Ass Barroom Brawler vs. a School of Hard Knocks Master. Interesting. The latter might be more appropriate for a bouncer (since he lacks the rage ability, and thus takes out the trash without getting huffy about it].
3. Is there a typo in the animal styles? Leopard, for example, suggests taking Dragon and Shaolin to simulate an animal style. I assume that should be Leopard and Shaolin.
4. "Know Your Enemy" --- great idea. Perfect for simulating a boxer or wrestler who has concentrated solely on fighting others with similar fighting styles.
5. A suggestion --- the charts at the end could be improved upon. For the style feats, just saying "Aikido Manuevers" for the benefit doesn't really help --- I still have to refer to the main text to learn exactly what benefits are conferred.
Working on the tournament fighter one shot. So far, I have a player who has called dibs on a luchador, so we'll come up with a Mexican wrestling style.
I'm also statting out a Roman Catholic priest from the Philipines who's a master of arnis [he hits your pressure points with two escrima sticks, but in a merciful fashion].
There's also going to be a Burmese bad guy running around...a master of Python bando, with snake tattoos running the length of both arms and a penchant for strangulation.
Since I have fun with character creation, I'm trying to stat twenty characters or so, all about 6th level [although I might end up raising that]. Then I'll give the players a summary of the options and let them each pick one. And then we fight.
