Seems ok! I like to get more RP, so this idea could actually help in getting more RP!
But in detail, I'm not sure if this
As we all know the one player in the game with 100 Piety becomes the pope and has all sorts of special powers and abilities and can issue papal edicts. Now if that person stays the pope it gets boring. I'm always looking for ways to inject some drama and intrigue into the game. So I suggest that the Pope can suffer a Piety loss If he dies. Everyone else suffers some skill point loss during death so why not the Pope?
In addition to that there should be Cardinals. Not in Official title but in terms of tier stats. I.e players that have 99 piety but cannot achieve 100 because someone is already The Pope. These Cardinals are the successors. If a Pope should die or suffer a Piety Loss for any reason they automatically become the next pope. The new pope can be chosen from the pool of cardinals by seniority. That is the person who reached 99 piety first and has been at 99 piety for the longest amount of time.
part would be able to be implemented this way.
But still, good idea! You get +1 from me for at least the goal of this idea!
