Markus “Notch” Persson was celebrating the continued success of Minecraft over the weekend, by playing a different block-based video game for once:

The above means that the total cross-format sales of the game now stands at a staggering 36-million copies between PS3, Xbox 360, PC and mobile formats.

Minecraft was released in alpha on May 17th, 2009 and sold its first million on January 12, 2011, less than a month after entering beta. By the following November, the game had sold more than four million copies.

It’s now the fourth-best selling PC game of all time, drawing level with World of Warcraft and only beaten by the first two Sims. It remains the only indie-developed title in the top 30 best-selling PC games.
