Ratchet is there because inFamous came out to make room for Ratchet... That will be moved come christmas when I expect to get another 4 games....
The reason KZ 2 is at the bottom is alphabetical. At the top, I have my top 3 games, and I rated CoD 4 above KZ 2, so that used to be top, and only now has been replaced by AC II. Modern Warfare 2 lives elsewhere
