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.
