Well, I can't say off the top of my head how many games I have, but it's a lot, especially if I were to add up my digital downloads as well.. I just remember what I have. That's one thing I couldn't possibly forget. I could also usually tell you how I acquired each game, whether it was a gift, or whether I acquired it myself. I may or may not be able to tell you what year, or who got it for me if it wasn't me, but I sometimes can, and can usually remember whether it was a birthday or Christmas gift. I bought the majority of my collection, mind you, so I may have difficulty telling you exactly when I did, but I can narrow it down to a certain period of time. I don't have any of the above written down, but I do keep track. I can't say I really think about it though. It just happens.
