It's possible to simulate the classical physics of fairly large game worlds using fairly small classical computer. If you wanted to model it using quantum physics instead (where quantum computers would theoretically have an advantage) said computer would need so many qubits that it would be much larger than the world it's supposed to simulate, while the additional realism would be essentially imperceptible to the player. You'd be better off using analog computing by putting a telepresence robot inside a real-world game arena.

Not really, almost everything is faked and not really a physics sim. Imagine a world like GTA but every material has realistic deformation and destruction.

I’m not saying quantum computers would be able to do that, but it’s not like current video games are at a point where more compute wouldn’t improve them.

Personally for me this is the relevant part.

I can ofc imagine some niche games like Kerbal Space Program with complete realism, but I'm not convinced it makes it more enjoyable to play. Would be interesting to see for sure.
