So I picked up the expansion based on this feature. (The other stuff added is cool too, but I really thought the idea of having AI generate the stuff for custom civs was awesome).
It seems to me there needs to be way, way, way, way, way, way more training for it. At least for the "image generation". I don't see how it's really "generating" anything when I see mostly the same images coming up for a civilization, regardless of what the description is. Super disappointed about this, but I hope it's just because it's early stages.
I havent even started a game because I couldn't get it to generate an image that was even remotely close to what I wanted. Even when I tried to make a civ of cats, none of the suggested ones had anything remotely like a cat (even though I've seen a few images in the past where it was basically a human with a cat head).
As for the text it generates, it's pretty good so far, although similarly, I think the AI needs to be trained on way more data because it tends to get repetitive very quickly (but I'm not really as concerned about the text description as much as the images).
Hopefully I can get over my OCD with the images and start a game lol.
