Factorio comes to mind. More of a factory builder, but I'd describe the gameplay as being a lot more about designing stuff and figuring out good solutions. If you have ever felt a slight bit of achievement after getting something to work in a programming language or some engineering discipline, this game will be like crack for you! And I do mean that literally. I spent 50hrs within a few weeks on it, loved it, couldn't stop thinking about it, felt like it was better than socializing and then realized that it took me months or years to get to the same playtime in any other game I own!
