1) Something I've noticed is that the AI rarely makes peace among themselves. I have seen Macedonia carry on wars with the Dardani, Getae, Bythynia, Lysimachids, et al from turn 1 to turn 100. Ditto for others like Seleucids, carrying on wars with Antigonid while Maurya is eating their lunch from behind. Doesn't War Weariness affect the AI?

2) Is it possible to get notice of wars and alliances amongst the AI nations on the right hand side? Maybe also a setting for which nations you care about to get notifications of?

3) I know this has been mentioned by others, but there really needs to be a way to give provinces back to your allies/client states.

On point one, I would guess that the special rules for the Diadochi are the reason. For Macedonia, they don't age in any turn that they expand, but age at twice the rate any turn that they don't. For the Antagonids, they have to have a certain number of wars going at any given time to limit aging. I'm not sure about the Seleucids.
