The official numbers from the NPD Group are here for June 2009. We first saw a estimation of the number of sales from
VGChartz.com. They estimated that Ghostbusters would be in the #10 position with 191,000 sales for the Xbox360. The NPD numbers cover 60-65% of all copies of the Video Game sold in North America, with the exception of Toys R Us and Walmart. Those additional copies sold are estimated to give a fairly percise number of copies sold.
Ghostbusters is no where to be found on the NPD Group's Top 10 for video game sales. The top 10 position was held by Infamous on PS3 with 192,000 sales.
EDIT: Through leaked info we have the data from NPD in regards to Ghostbusters: The Video Game. It sold the following amounts:
Xbox360: 192,298
PS3: 103,413
Wii: 71,899
PS2: 43,420
DS: 29,059
(PC Sales is not represented in NPD Data).
If those numbers are close to being correct, it is still $25 million dollars worth of sales for Ghostbusters: The Video Game. Here is hoping that Ghostbusters will be seen sucessful enough for a sequel or even more. That being said.. if nearly 500,000 copies were sold... where are all the fans?
