Games I own but have yet to open or play.
Yes, I am a consumer whore. Sometimes I see a game that is a fantastic bargain, or something I had some degree of hype for in the past, and I buy it on a whim.
Then somehow they fall through the cracks or just can't muster the interest to actually play them. Even worst than a game you own and never finish is a game you never start.
This my TRUE pile of shame. I'll play them some day, I swear! As soon as other games stop coming out...
