Minecraft hits 5.2 million sales, still a secret yet to find, says Notch

Markus 'Notch' Persson has confirmed that Minecraft has now sold 5.2 million units since it first went into a public alpha state in 2009.

But speaking at a GDC interview session, conducted by SpyParty developer Chris Hecker, the Mojang co-founder spilled that there's still one secret left in the game that has eluded even hardcore players.

He also explained why there was no female character model in the game.

"It ends up being extremely sexist," he said.
