It's not something I'd "like" to believe. I'm a PC gamer, so I would love for it to have as significant a market share as possible.
If those numbers exclude digital sales and the PC share is in fact much higher, that's a good thing.
Jeez my fellow PC gamers are insufferable aren't they.
I'm sorry but you're on GAF, ignorance is going to be called out. If you don't want to be called out then do your research.
It has been known for years now that most retail data sales exclude digital sales since you can't even get the exact number from some sources unless it comes from the Developer themselves. I would think to a self proclaimed PC gamer, this would be common knowledge.
