I recently played The Planet Crafter. Some similar concepts to factorio, but not quite as deep. But it becomes wonderfully colorful.

Some observations - get off a planet, but in first person perspective. No guns/fighting. Less of a time suck than factorio. Upgrades seem to be less tightly tied to exactly what you do. It's somewhat unclear how to even know how to progress, but maybe it doesn't matter. When automation becomes available, it is easier. There's a struggle for food, water, air at the beginning I didn't like at first (even in menus it doesn't pause). I learned to accept and enjoy it though, and things you do make it less of an issue.
