Didn't notice that much fail, its not perfect but AI do well in most situations. I had quite a few trouble fighting Ottomans, they keep their 30 stacks close and they are very hard to defeat. AI goes for objectives and if player retakes it then they try to retake it again. Its decent, they capture forts etc.. I got dowed and dogpiled quite a few times by AI, they seem to know when to declare war.
- I've seen some Spaniards again running through Africa and Anatolia to return to Spain tho...
- AI also seems to rarely (if ever?) cancels their movement even if its not locked yet, so they bumped sometimes into superior force and die. This happens sometimes, not too much it seems.
- France also failed in my QQ game, they kep 70% their original territory. England was fine. Commonwealth is waaaay OP bossing HRE around. Russia formed, killed hordes, entered Sweden and colonized all Siberia.
- Bahmani's hold 90% of India etc.. doesn't look too wierd. edit: they formed Hindustan lol, never seen AI do that..
- Ming is also well and alive in 1650y
