No Forward Settling = No War

[The_goggles_do_nothing]

I've observed that if I'm careful not to forward settle the AI, they don't seem to declare war, even if I don't have a good relationship.

Unless they forward settle you. Even after the patch, the AI makes some odd choices.

I stole an entire Nat Wonder from Isabella with my expansion city and she did nothing about it except whine in the Modern Age, on Immortal. In the same game Bolivar forward settled me and declared war in Ant but was begging for Alliances by Modern.

I think it has to do with a lot more than just forward settling.

Mileage may vary.
