You're already overthinking it with AI and stuff; there's games (especially on mobile) with minimal input requirements, think flappy bird, runner games, some of the racing games, etc. Even Epic's first major mobile title, Infinity Blade, played more like a slow interactive story than something needing lots of control input.

I mean I won't claim they're fun, just that they're easy to play.

Your argument would also refute the whole co-pilot experience itself. It is not about "there are simple games, go play that". It is more to enable them to play anything.

I think anything that can be co-piloted so smooth that other player is not annoyed, can be also simulated by an AI.

It is not really overthinking it. It is taking the learning and bringing it to a wider audience.
