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.
Not... at all? I mean, Vim has a steep learning curve[1]. Factorio is a game meant for the masses.
Of course any game is hard to master, but in that case any game that is not made for 3 year olds has a steep learning curve. You won't know how to set up and manage a 1kspm factory from day one, but that's okay, you can start by exploring and have a lot of fun doing that.
