I've been using the Kitsunemori Campaign Setting Prestige rules: Characters start with a prestige score equal to their WILL score. You can use it for prestige contests when staring each other down ("pulling rank"), or against a DC to see whether villagers or other people recognize them. Use DC 5 for populated regions and DC 20 for hermits... Whenever players do foul or noble deeds, they get to check prestige: If 1d20 + prestige bonus > current prestige, their prestige rises by 1 if doing noble deeds; if the test fails when doing a foul deed, prestige drops by 1 instead. I've used it when players paid respecct at a famous shrine and when players entered a new village.
