Killzone sales

[FishyJoe]

If we don't know the type of sale, retailer or consumer, it's impossible to compare it to other games sales wise. NPD, VGC, Famitsu, M-Create, Chart Track all record consumer sales. Company sources often quote retailer sales, which are often quite different from consumer sales.

I'm not saying one shouldn't include greatest hits sales, but it should be noted as according to the article it sold 50% more as a greatest hits title. If one accepts the 2 million sales total, this means only 800k were willing to pay the full price for the game.
