oh buddy, I … I’ve got terrible news for you …

Avasarala is my pick

Then just go for factorio. Randomly generated map and recources. Highly adjustable for dificulty and a LOT of mods that add to the game. Concidering that the dlc , that seems to be as complex as the Base Game, comes out in Oktober you have a good Kandidaten for infinite replayability

And latent heat of vaoprization!
