The AI completely ruins the game with its warmongering
For context immortal difficulty. No matter what i do every game I get warred on by civs halfway across the map for no reason. As soon as i get through the boring early game min maxxing everything to finally be able to snowball and overtake the AI they declare war on me after moving an army from halfway across the map. Neighbours are guaranteed to war you no matter what you do. There is no diplomacy at all. You can give them all the land they want. Do nothing to antagonize them they don't care. You trade luxes with them, declare feiendships all of that meaningless. They'll just end up declaring anyway. They can't kill you or take your cities, just to waste your time and ruin the experience. I still end up winning but it's 0 fun. Can't spam wonders, can't grow tall. Just forced to bee line victory conditions and spam science and the rationalism tree. Don't die and it's a win but with absolutely 0 fun because the AI makes it its goal to just do the most stupid shit. Alexander has 3 neighbours next to him he'd rather march through all their territory to go across half the map (literally) to attack me for absolutely no reason. Don't wanna play stupid minigames of paying them gold to war on each other. That's not Civ. There should be reason behind their actions. A shame really because i enjoy many aspects of 5 over 6 but this completely makes the game boring to play and win on immortal or deity. They will just permanently declare war because of the ridiculous production boost they get to units (great design by the way).
