So a big reason that you can't find good data on CiV sales is because it isn't really made publicly available anymore. Steam has always only reported back to the publishers, and now NPD no longer publishes their data. Basically, there is no reliable source anymore, sites like the OPs are dubious at best, and we're forced to hear what the publishers tell us. It's frustrating as a fan who just wants to know how a game is doing, but there is a reason for this. NPD's data was becoming increasingly inaccurate since it didn't properly account for digital downloads, and even when the data was accurate it was leading to situations like my previous post where publishers stocks were becoming wildly volatile with each major release. The "video game industry analyst" groups are a joke, and you combine that with the heavy involvement of day traders in video game stocks and you wind up with massive fluctuations in stock prices based on a single weeks worth of sales for a single game, despite the fact that its all but irrelevant to the bottom line of a company as massive as EA, Activision or even Take Two.
