Smash ultimate on Switch. primarily "story mode", although it starts to get boring by now... Have three pending switch games (monster hunter, Mario party, splatoon), so I will probably change soon.
Cities skylines on PC. I am addicted to that game, and other simulation games. I mean, I even got addicted to mini metro, which is nothing more than drawing some lines between dots...
and sometimes some Reactoonz, Moon Princess, Jammin' Jars... But those games can cost way too much money so I cannot recommend them to anyone.
