So far: Seven items that were not on my collection. Some were pretty surprising to see. Why weren't 24, Marvel Vs Capcom, We Love Katamari and Viewtiful Joe in my collection?
And EVE: The Lost One. I don't remember how I got that one.
Nine: Cool Boarders 4. I still remember buying this game, brand new, and I got it for a buck because the guy who sold it to me loves my business. I always buy tons of music off of him.
