Trump works for what ever makes trump look good. He will eventually fire Musk. Are there odds on musk making it the full 4 years? Remember he was also in the first administration, but got out.
No, Trumps successor will be family. Or maybe Kushner
I want to add on that Sid Meier had a philosophy called the one third rule, where on third of a new game would be kept from the previous, one third would be improved systems and one third would be new. I don't think he is big into the studio at the moment, but i can see him still being a guiding light.
I don't play many games, but civ patches will get the game polished and it will be a world better at some point. Until then, you can be the part that is booming the system or wait until the product is in a place that the community loves
