I'm halfway through SPQR right now and I have a little over 40 provinces and around twice that many generals. By the endgame, it's probably going to be 4x that number. Micromanaging will become a huge chore.
As such, I'd like to develop a mandatory retirement age for my characters, that way I don't have to micromanage and think about it. I've stacked a lot of nice ancillaries that I'd like to transfer before characters die. Does anyone have a statistical breakdown of the chances of a character dying certain ages?
