It is interesting to hear a similar feeling (I use to be heavily addicted prior to university). While I still do play games, I focus on short ones (story-driven like Life is Strange [1]) or ones that can be decomposed into intensive moments (e.g. StarCraft 2, Doom 2016/Eternal [2], Black Mesa, Ori and the Blind Forest/Will of the Wisps).
I am not even tempted to play games that are work, or longer endeavor. To the point, that while I love the Witcher universe (read all books before it was cool; like, 20 years ago) I decided to rather watch all cutscenes than play. (I call it gaming porn.)
With Factorio - I know that 15 years ago it would totally addict me (I was to SimCity, and Transport Tycoon Deluxe; I have a kink for building and maintaining systems).
Now... emotional catharsis, or intense flow of shooter, is what I play for. Working for dozens or hundreds of hours - I prefer to spend the time creating something. It is not (only) "I am adult and blah, blah" - just I know I would feel nauseous guilt on one side, while some sense of accomplishment when creating something for others.
I've found that I am still willing to play RPGs that have some decent plot or game mechanics, but only if I'm able to skip past the grinding phases—either through cheats or by playing older games in an emulator with a literal fast forward button.
When it comes to city builders and similar games (including Factorio), I'm too easily distracted by the metagame puzzle of wondering about optimal strategies. I can't play them for long before I end up closing the game itself and pulling up documentation about the game's rules and internals, and that usually breaks me out of a potentially addictive cycle.
