The NPD numbers show an interesting battle between two similar games: Prototype and inFamous.
Excerpt: "Now, however, that the June NPD numbers are out we can finally declare a winner and put this to rest as early reports had inFamous selling around 190,000 copies for the first week, but the NPD numbers had a weaker showing of 175,900 in May. The June numbers show an additional 192,700 for inFamous, bringing it up to a total of 368,600 since launch while Prototype racked up 419,900 on the Xbox 360 alone. We don't know the number of PS3 sales, as it apparently didn't make the top 10 reported by NPD - and PC sales are currently unavailable.
But even without PS3 and PC sales it would seem that Prototype has come out as the fan favorite over inFamous."
