In a broader sense, the best games are fun to simply exist in. Getting from point A to point B should be interesting from a movement perspective.

Mario Odyssey is a great example. Just parkour’ing around is a blast.

BotW has shield surfing and such.

Lots of shooters have a bunny hop mechanic.

Wave-dashing in Celeste.

Etc etc.

Humans and LLMs learn in fundamentally different ways, though.

The nuance bit is really interesting, since I feel that nuance arises from these fundamental differences.
