The opposite would be correct. AI generated is the norm, and it would be impressive to spend xxx hours creating this when AI can do it in 4 hours

Definitely smells like ai. I don't think a human would spend so much time on the graphics and effects and not have streamlined the gameplay a bit.

What does AI generated even mean, really? Because there is a pretty big difference between “make a star craft game” and a sequence of very specific small prompts to build it up. They are both AI generated, but will vary wildly in quality and implementation.

Assets are very easily duplicated because of the editor that ships with the game. Not as impressive as it would be if it were other games with more tightly-locked assets.
