Minecraft PC sells 8 million

Minecraft is already a big hit, but now it's even bigger. The PC version of Mojang's open-ended creation game has now sold over 8 million units, according to the game's official website.

Creator Markus "Notch" Persson commented on the sales milestone on Twitter today, saying, "My face is making grinning sounds, so I assume it's grinning."

This latest sales milestone for Minecraft comes after the game became available via download card at major North American retailers like Best Buy, Target, and Wal-Mart.

Minecraft may have originated on the PC, but that is not the only platform the game has seen success on. The Xbox 360 version has sold over 4 million copies since launch in May, driving $80 million in revenue, with the mobile version selling 700,000 units as of January.
