I have played multiple different sized FFAs with hard AI, I noticed that Maurice(Dutch) is the most annoying, it masses only artillery and stays defensive. Second most strongest AI is Elizabeth(British).
The native american AIs are always the weakest while the Asians are the second weakest.
Please devs balance the AIs, it doesn’t even feel like they are playing on the same level. Not even close. In its current state some civ AIs are way too strong while some are way too much weak. It is always predictable which AI will be wiped out. The player scores immediately start having a huge gap.
