Why the outright ban tough? You could instead have made the rule that things with AI generated content have to be tagged with AI assisted or AI generated as tags, without needing the ban on it. People that are against the use of AI for content creation could easily avoid those games then, while playing the rest. It is pretty easy to avoid it since only one game used it last year which is skyes game.
I really don't see the reason to ban AI outright instead of going for those other options first.
