Age of Empires 3. Moved to the DE version and I enjoy knocking about in it when they do the events from time to time. I’m a sucker for collecting things, so currently started on the March Madness event. It’s probably the game I’ve played the most apart from WoW.
Other games I’ve parked up, but do enjoy from time to time are the old Gold Box Games from SSI. I particularly like the Pool, Curse, Secrets and Pools series. They got a cool mod for them now which improves the QoL in the games.
