For games none I can think of off the top of my head. I have, however recently bought the complete box set (5 seasons, 100 episodes) of Stargate Atlantis on Blu Ray despite owning the DVD box set. I love that show, and while it was a chunk of cash it was well worth it.
EDIT: Just remembered I own a Steam copy and a physical copy of DEFCON. Though the Steam copy was via a humble indie bundle, but it's an awesome game.
