Right, so, I don't know if people have single bad experiences with the AI to share or just overall disappointment, but I thought I'd celebrate my signing up with a thread.
So, if you have bad AI experiences to share, go ahead.
Mine:
I'm attacking Japan's city with two swordmen, a knight, a crossbowman and a catapult. The swordmen are getting old and are pretty useless, any attack by them is a major defeat, they're pretty much just sitting there. Without Japanese reinforcements, it's only a matter of time before I grind the city down.
Then, oh no... a Samurai is produced in the city. Suddenly the city seems to stand a chance, if the Samurai - together with the city's defences - can kill one or two of my partly-damaged units. What does the Samurai do? It backs away. Okay, maybe it's going round the single mountain tile next to the city to attack from the side. No. It simply backs away and disappears into other parts of Japan's territory. I never see it again. A couple of turns later I take the city. I feel no satisfaction, only disappointment. How are we expected to enjoy a video game if the AI is this bad?
A simple "attack enemy on-sight whenever possible" programming would be better than this crap.
Disclaimer: I'm only a couple of weeks and a few games into my Civ6 experience, probably don't know everything there is to know about the game.
Anyway, share your disappointing AI experiences if you feel like it.
