When I change from one of these activities to the other, I have the distinct mental impression that I’m not switching activities at all. When I switch from Factorio to my text editor, it’s such a seamless transition, as if I’m just scrolling to another part of my factory.
Not a sensation I’ve had with any other game, or any other pair of distinct activities, really.
I figure it must mean Factorio makes me a better coder. I better get back to it, then!
