In one of my IRL games we're trying something new. I'd implement it in one of my games, but I'm not planning on running anything new for a while.
But here's the idea: Beliefs and instincts. On the sheet, each player picks a few beliefs (say, 3) and an instinct or two.
Beliefs are general guiding principles. They could be related to the character's overall goals or just general ways of dealing with the world. They give the player a direction to RP in and give everyone a succinct idea of what the character is about. Examples of beliefs would be "It's only wrong if you get caught," "The past has an answer to everything; you just have to know where to look," and "(insert faction here) is too caught up in infighting to make any real change."
Instincts are just that. They're the first thing that's likely to occur to your character in a given situation. So, if your instinct was "When entering a room, check for traps," and the GM tells you there's a spike trap, you can reasonably say that you avoid the trap by citing your instinct. Another instinct might be "At the first sign of trouble, ready my sword."
Meanwhile, the general consensus seems to be moving toward personalities being baggage on a sheet that frequently gets ignored. I think this might be something that could be shorter and sweeter, without the high chances of being ignored right after the sheet gets made.
Thoughts?
