You know that scene where the ninja kills, like, five guys in one round?
I’d like to see a mechanic where ninjas must deal with things that happen too fast to react too. Maybe instead of things happening once per round, some things can happen “between rounds”. The only way to deal with them is to pile up some kind of debt. The deeper the debt gets, the greater the results of failure. Part of the game then becomes trying to get into a clear space where you can rest for a beat and clear your debt.
That is bad ass, and I would love to use this in play sometime.
