I remember one looking through the rule book for a Buffy the Vampire Slayer RPG which had an interesting concept: players had a certain number of "plot points" (I forget exactly what they called them) which allowed them to overturn an unfortunate die roll. It was based on the idea that in the TV show, the main characters would often manage to get out of a tight spot through well-timed luck.
