Mostly Cities Skylines 2. The performance is not great, but it's passable with the settings turned down and the actual city building is really good. Right now I'm working on a big expansion to my city further down the highway, just got the water/power lines run between them so it's one big happy grid exporting the extra to other cities. Already looking forward to the things I'll do differently in my second city!
Also playing some Super Mario Wonder on the side, which is fantastic. Great mix of easy fun levels and hard-as-nails secret special levels. Very fun!
I've got about 100 hours in and I really enjoy it. Performance isn't great and it's gotten a bit crashy now that my city is really big, but the game itself is a lot of fun.
