I only bothered checking 2 prices from your list: Mass Effect 2 and Resistance 2 on Amazon.com.
For Mass Effect, you used the cheapest price available (49.99, not actually from Amazon but a partner) where as for Resistance you used the highest (57 from Amazon, but could be had for 34.75 from a partner).
Could this be a simple mistake? Absolutely, but if there are errors in the first comparison, I wonder how many others there are? Sadly, I'm too sleepy to check, so will only comment, that I have no comment as I don't trust the veracity of the data presented at this time.
