Shapez is much more guided, abstract, but probably still as complex as factorio.

Mindustry is simpler in complexity but much more aimed at "tower defense" style game play.

Satisfactory is like the child of Factorio and Subnautica, with a little of both games but not as deep as either.

Dyson Sphere Program is probably the truest successor to Factorio, but it's still very early access and just now adding combat.
