I buy almost all first party on Playstation as well as Nintendo systems. Batman, GTA, and Skyrim are the only 3rd party games/franchises in my permanent library (well some exclusive 3rd party games like Beyond have made the cut technically). I get plenty on Plus and while entertaining, I usually don't replay them. I buy a lot like Tomb Raider and FC3 but after an initial run or a platinum I sell them.
