I really like to play with mods, especially the tech ones, I enjoy building automated processing systems and factories and bootstrap myself in the style of "The Mysterious Island". Here's a game I really wish would exist (and I think it will, eventually):
Actually, there's a game about building factories and automating the hell out of it.
It's called factorio.
But admittedly, it's not realistic, not even close. But I do spend the vast amount of my time thinking about logistics.
I know Factorio, although I haven't played it very much. My thoughts exactly - it teaches kind of engineering, but the realism is lacking.
What I would like to see from the game is less focus on how are things laid out in space (that's a different puzzle) and more focus on what crafting materials to use and what their different tradeoffs are (physical and chemical properties, cost, processing complexity).
