There are many PC games that have sold incredibly well such as SimCity 300 at 5 million units or Guild Wars at 6.5 million units, but there are only 5 that can be called the top 5 best sellling PC games of all time
(Battlefield 2, EA, Industry, PC, Tech, The Sims 2)
Of course they're going to miss is it, because this pathetic excuse of an article is using wikipedia entirely as it's source. I'm not bashing wiki here at all, because at least the wikipedia article listing the games by sales actually mentions the important part - doesn't include 'sales from digital distribution stores (such as Steam, Direct2Drive, etc.) are omitted as a result of the NPD Group and similar organisations being unable to accurately track these sales'
Considering the modern face of PC gaming that is an absolutely huge omission. It'd be like excluding console games sales from US store Gamestop or UK retailers GAME (and almost identical sister store - Gamestation).
It is kind of ironic though, that digital distrubtion has made sales data almost impossible to obtain, when it in theory would be very easy compared to retail.
