Satisfactory, in early access on the Epic Store.
It’s like a simplified Factorio in 3D. Lovely graphics, and building HUGE factories is so simple. There’s nothing quite so satisfying as planning out an assembly line, constructing it, getting it all perfect, and then hooking up the power and watching the affront to nature you just created whirr into life.
There’s a distinct lack of “end game” at the moment, once you reach the current tier limit for early access, but more content is on the way.
If you enjoy Factory Automation games, it’s definitely one to check out.
