Funny. I did the same thing. Bought Satisfactory but haven’t even loaded it up yet because Factorio sank it’s hooks into me yet again.
By the dev’s definition? No. By any reasonable standard? Hell yes. It was an amazing game years ago and since then they have just kept polishing till it had a mirror finish. Let me temper expectations though if you have never played it - they are actively working on the newbie experience now including tutorials and the intro campaign. All of that polish I am talking about above is for after you know how to play. It’s just a deep game with an endless supply of things to learn.
