I'm not into buying games digitally, and the only digital one I have I also have the physical copy of. Besides that me having Steam is basically only a thing because I needed it for my Total War games.
Digital: 1 - Star Wars: Knights of the Old Republic II (I wanted to replay it but I was too lazy to get my disc out and it was just €2)
Physical that needed Steam to be activated: 4 - Empire: Total War, Napoleon: Total War, Total War: Rome II, Cities Skylines (even bought two DLC packs for this)
