If you're not familiar with Zachtronics' games and SpaceChem, it's basically going to be in a similar vein as Factorio, except perhaps with more focus on automation, so it's definitely not going to be another Minecraft spinoff. Zachtronics is all about automation and programming games, albeit there is rarely combat element involved, and if so, in a programming-game type of way (such as boss fights in SpaceChem, where you basically build contraptions that self-destruct in a specific way in order to do damage to the boss), so it's not going to be exactly like Factorio either. They also like having some story going on in background as you feel your brain cells overheating.
They have free browser games on their website if you want to get a feel of their style. They are all very good ones, although you might want to have a degree in engineering before playing.
