I don't see much similarity between Infinifacory and factorio other than they both have conveyor belts. Infinifacory is much more like a 3D version of SpaceChem. It is a puzzle game where you are given certain inputs and have to create different outputs. I only completed a few so far but am enjoying...

I'm pretty sure if you bought "Banished" from Luke's website he also gave you a Steam key.
