Since Musk and Bezos are actually building rockets I'd think they'd find a simulation to be less fun in comparison. But maybe they'd enjoy it the way a chess grandmaster enjoys playing blitz as relaxation during a break in a tournament game.
Musk is already playing a game; it's called "the simulation", and we're all in it. I'm not joking; according to him, we are most likely in a simulation. [0]
