arcady said:7th Sea had an innovation I've yet to see resurface, but if it does it could completely rewrite one popular aspect of nearly all non D20 based RPGs... In 7th Sea disads/flaws cost points rather than reward them, but give XP when they come up in play. Thsi completely flips the axiom of disads from something the players try to trick the GM into avoiding into something the players strive to have actively hinder their characters. Couple that with a good list of disads and you could go a long way towards encouraging roleplay and actually getting people to enjoy roleplay who were not previously inclined to it.
But now I'm going back in time, if I keep this up I'll end up on a discussion of Dice pools and generic RPGs... Let's move forward...
The Babylon 5 rpg used that too. Don't laugh.

It's a great mechanic and I intend to use it whenever they come up with a advantage/disadvantage system for Exalted.
