Back in the old West End Games d6 days there was a space on the character sheet for a character quote.
Out group took this a step further. If the players used their quote in a game appropriate time, they gained an extra character point at the end of the session (XP). It added some extra fun to the game, and was very Star Wars (eg "I've got a bad felling about this", "We're doomed" etc)
I am thinking of bringing this into my AoR game. Instead of XP, I will give the player a Boost die for their next roll. Does anyone do anything similar?
