Likewise; I think that's because (my interaction with) Factorio is much simpler; it's scratching the "build and organize" itch. I find this game to be relaxing after a hard day at work. (I'm sure this would change if I was trying to build and debug a complex circuit network).

As others have mentioned, Zachlikes are basically programming, and in particular the debugging / pipeline optimization parts can quickly drain my enthusiasm if I've been doing a lot of hard coding at work.
