After researching the million-selling games available for PlayStation 3, I thought it only fair to follow that up with the Xbox 360’s million-sellers. Listed here are all of the Xbox 360 games that have to date sold over one million copies worldwide, based on the latest and greatest information I had available. Likewise with the PS3 list, there are some games (like Madden 09) that I could not find current numbers on, but we all know Madden 09 sold more than a million copies (EA says they sold 4.5 million) and would likely be higher on this list.
