It's worth noting that no one has really good data on game industry sales. The comic industry has Diamond and they have such a monopoly on sales that their lists are a pretty accurate indication of what's going on in that field. The game industry has Comics and Games Retailer and ICV2. Comics and Games Retailer collects reports from retailers each month and they make some lists based on that data. The trouble is that it comes from a self-selecting pool of retailers and their info may or may not be indicative of what's going across the lion's share of stores. ICV2 puts together lists quarterly and they talk to distributors and others to find out general trends. It's hard to say how accurate their information is. That's why throwing around any of this data as proof of anything is a dodgy proposition.
