I've been playing the hotfixed 6-22 version and I can confirm that AI is not doing anything particularly weird when it comes to war/peace logic. There is plenty of fighting. However, due to the change made to Open Borders logic, I am seeing fewer DoFs, especially mid and late game as Civs are less keen to just open their borders to anyone that asks. This has also been slowing down the rate at which Tourism builds, which has had a very noticeable effect on the ease of a Culture victory. In my most recent game as Egypt (Emperor/Huge Map/Epic Speed) the game is in the early Industrial Era and as the Tourism leader I've only been able to become Influential to 3 out of 13 Civs, whereas in past games where I focus on Tourism I usually have most Civs Influenced and just wait for an Ideology or a Great Musician to end the game. Now it looks like I'll actually get to use Archaeologists, Museums, and Broadcast Towers, whereas in past games I could achieve a Cultural Victory before these techs ever came into play.
So great job with the balance changes in this latest version, G!
