I wonder how tweakable those generated images are. The most important requirement for 'game art creation' is that it is created in a tight feedback loop between an artists, an art director who needs to enforce an overall artistic vision, and the cold, hard requirements of the game design.

Can I tell the AI "that looks great, keep the trees and house, but I need the door on the right side, and the sky a bit less cloudy". Will it be able to incorporate such instructions without "remixing" a very different image? Can it "understand" the suggestions the same way a human can without having to go into so much details that it essentially becomes procedural generation? Is this even something that's possible with the current approach?

If that's not possible, then I can just as well google and hope to find a matching image.
