How to award players who embrace the downsides of the character they display? Like when a dwarf gets drunken right before an epic fight, or a kleptomanic thief refuses to flee from a sinking ship full of gold?
I need to deal the downsides, that´s the point, but I want to give them some award for being authentic and making a better game. Here are my ideas:
1) Fate-Points or alike. I dislike the idea because the usage of those point is in no plausible fictional way related to they earning.
2) Gaining XP. I dislike the idea of characters acting stupid just to level.
3) A custom move.
When you act on your very nature and embrace all the consequences, roll+nothing. On a hit, the immediate result is somewhat under controll. On a 10+, you get to shine.
That´s a very vague definition to be polished, but I picture a drunken dwarf with his warhammer stumbling throu the frontlines, beheading orks without even noticing the danger.
What do you think? How do you handle that?
