Inspired by the Duty mechanic, while taking a shower I thought about a different idea about what happens when group obligation reaches 100 (I really hate the current mechanic o limiting experience/character progression).
Once group obligation goes over 100 two things happen:
a) The group gains Notoriety rating 1
b) Obligation ratings reset to 0. It doesn't mean they go away - the characters still have debts to pay, bounties on their heads, etc.
Notoriety means that people just don't want to deal with characters who are in so much trouble - they are reluctant to help, suspicious etc. Notoriety also means that all those burdens weigh the PCs down and remain as a shadow on their thoughts. Translated into game mechanics it results in upgrading all social checks by 1 and (or?) decreasing ST by 1.
Once the group "cleans" 100 points of Obligation, Notoriety goes down.
What do you think?
