Heavily recommended to any management-sim fans. It takes the best mechanics from games like The Sims, Factorio and Dwarf Fortress without watering them down or limiting the modding community. The price is on the steep side, but the developer is great and works with the community plus releases native builds for Mac, Linux and Windows.
We've both sunk uncountable hours (actually we started way back in alpha 15 with a pirated copy so steam hours doesn't mean much) and done many campaigns with many mod loadouts. Yet to actually "beat" the game (it's not really the kind you "beat" though, it's very sandboxy). So entertainment/$ is astronomical.
