to think AI art is theft while also thinking making a game about Back to the Future isn't
Good argument. Also, it is not even established what AI was used and how it was trained. (or that it actually is AI made. Just some commenter claimed it was. Could also just be old fashioned tracing.). But the AI haters would not care, even if the AI would be trained ethically by consenting artists and public domain art. They do not even understand how those tools do their magic. It is even possible to train an AI on your own art for crying out loud.
But yeah, complaining about the AI stuff on a game with no original charactes is kinda ironic. Reminds me of someone complaining about the "ntr" of a son watching his mother have intercourse.
