For me it's Satisfactory and Big Ambitions, and to a lesser extent strategy games like Civ. Atlas used to be on this list before the devs destroyed it then ran away. Racing games are also good for being replayable whether you are playing against AI or people.
Big Ambitions just has so many options that it's different every time I play it. So many different types of businesses you can run. And the properties are randomly generated as far as what is available any given game. Also, they've had major updates every few months ever since it launched that have added a bunch of new content.
Satisfactory involves a lot of building and you can try different things every game.
And obviously games like Civ or Stellaris play out differently each time.
