Right now I'm doing a (local) co-op play of Crusader Kings 3. Usually only on Sundays.
It's loads of fun.
Ones I want to play co-op are Victoria 3 and Stellaris. But I'm probably the only person who enjoys the Victoria series. It's kind of similar to Dwarf Fortress in that it's heavily based on a crafting economy with lots of automated factories. Most of the complaints about the series are that they don't like the low-combat focus - and Victoria 3 gets the brunt of it because it ended up with mainstream exposure while Victoria 2 never enjoyed anything close to that level of success. I think the entire community was something around 3-4000 players in total at its highest popularity, but those of us who liked the game, liked it a lot. Victoria 3, despite the negative response, still has a significantly larger fan base.
I describe myself as a little dose of toxic masculinity.
