I've spent way too much time both playing and finding engineering-focused games, and haven't been able to find very detailed or comprehensive lists online. So I made one :)
These games are both fun and often quite educational, presenting gamified versions of real-world challenges and professions.
There's a lot of different sub-genres of "engineering game", such as:
* Factory automation (Factorio, Dyson Sphere Program)
* City builders (Cities: Skylines, Anno series)
* Route-builders (Mini Motorways, Railway Empire)
* Comp sci (TIS-100, Bitburner)
All games on the list are very highly reviewed. I've played most (but not all) of them, and provided personal recommendations alongside the reviews. Many of them are also playable on GeForce Now (if you don't have a gaming PC).
Please contribute if you know of more, or have any comments/suggestions!
