Tried a new game with the latest beta v4, it feels very similar to 1.10. I think the forward-settling is better, the AIs mostly expanded in sensible ways (with the exception of Egypt who seems to be broken and settle in crazy locations every game). I did DOW on Hatshepsut very early on because she put two undefended cities deep into my empire. I was able to take them easily as she didn't ever send a single unit to defend them. I played out the rest of antiquity in total peace, even though almost everyone was furious with me for most of it. Hatshepsut marched a large army to my borders a short time after our war ended, but she never declared on me. None of the AI players ever declared war on each other. So all told there were no wars declared by the AI at all, and one war declaration by me.
edit: deity/marathon/continents++, played as Ibn/Aksum, no other gameplay mods (just UI).
