With the caveat that Factorio is EXTREMELY addictive, properly described as "programmer crack", here are some other Factorio related discussions:

Mapping Factorio with Leaflet (cloudflare.com)
Factorio does have a rather steep learning curve, and the UI is not the most intuitive. But. Once how it works clicks, it clicks, and suddenly morning. And I'm in my 40's, I'd thought my days of unexpected overnights while working on fascinating problems were mostly behind me. Highly recommended, but be aware.
But wow, what a great game.
There are lots of games I can play for a specified amount of time and be fine with it. Pretty much all of them, really. Factorio, I get annoyed if pulled away in the middle of a project. So now I know to not even start unless it's free time for the rest of the night.
