>"After reading the interview, I went back to my own conversation with Raptr CEO Dennis Fong, who reminded me there are a staggering 900 million PC gamers worldwide. Contrast that data with global consoles sales of, say, Nintendo's Wii, Microsoft's Xbox 360, and Sony's PlayStation 3: About 262 million units. Combined. Granted, that's according to VGChartz which isn't a perfectly reliable snapshot, but even with a considerable error rate that tells a compelling story. The most popular game console to date is the PlayStation, with estimated global sales of 157 million."
