These are the games I've completed. There might be some titles I'm forgetting but for the most part, I'm pretty selective with what I play.
If you're wondering I purchase all of my games digitally now when I can. Sure, it's nice seeing a collection on the shelf but I own a significantly big DVD & Blu-ray collection as it is. Plus, I like my games to be compact and available in one place anytime & anywhere. I think Steam changed my perspective on things.
