Why doesn't vgchartz post PC game numbers?

[Bodhesatva]

SSJ is correct, for the following reasons:

1) An hugely disproportionate amount of PC sales are online. Valve recently stated that half of Orange Box's PC sales were through Steam. Some enormously succesful games like Bejeweled can't even be purchased in the store. Since we can't track online sales in the same way, that's a problem.

2) Many other sources don't track PC sales. Because we use sources like NPD, Media Create and Chart Track to correct our figures if need be, this is a problem.
