From my games, I seem to have detected a trend that the AI nations do better when the human player is also doing well. In my hands-off games as Zimbabwe, doing nothing, most major AI nations also seem to be doing poorly - the Ottomans barely make any inroads against the Mameluks, Spain barely gets a foothold in the Americas. In my current game as Austria, I'm spreading across southern Europe; and the Ottomans have already conquered the Mameluks, Spain is totally trashing every pagan nation in the Americas, my neighbor Poland is still strong (and doesn't get crushed by Russia like usually). So the question here is: coincidence? Or does the AI have some sort of "incentive" to do better if the human is also getting strong?
