The thing is that it’s kind of voluntary. Game developers could have use AI to develop the game and if they wouldn’t want to disclose it no one would know.

Unless the use of AI is the very crappy “AI art” that’s easy to notice the rest of uses would be very hard or actually impossible to figure it out to audit the legitimacy of the tag.

And this will end like r/art where the mods deleted a post accusing the artist of using AI when it was not AI and the final mod answer was “change your art style so it doesn’t look like AI”. A brutal witch-hunt in the end.
