People look at me funny when I say this, but it's true.

I work in performance - a space where we're thinking about threading, parallelism and the like a lot - and I often say "I want to hire who play with trains". What I mean is "I want people who play Factorio", because the concepts and problems are very very similar. But fewer people know Factorio, so I say trains instead.

I think I know why it's enjoyable even though it's so close to work, too. It's the _feedback_. Factorio shows you visually where you screwed up, and what's moving slowly. In actual work the time and frustration is usually in finding it.
