In my defense, at one point my Xbox 360 was so on-the-fritz that I thought I would have to rebuy most of my library for PS3, but thankfully a new power brick solved that problem. Many others were part of collections for major discounts from the original price. (For instance, the price of the “Burnout Collection” was only a couple bucks more to get a new copy of “Burnout Dominator” with the two other games in the collection, rather than merely getting a used disc.)
