Minecraft is a neat little indie game that until this week had been getting by on word of mouth and forum recommendations. All that changed when Team Fortress 2 developers Valve gave the game a shout-out.

Since highlighting the game in a recent Team Fortress 2 blog update, sales of the game have gone through the roof; of just under 39,000 total sales since the game went on sale in 2009, over 3,000 of those have come in the past three days. At €10 a copy (around USD$13), that's a healthy week's pay for the game's creator and lone developer Markus Persson.

Of course, you don't have to pay to play Minecraft. You can also sign up for a "Classic" account and play the game's bare-bones mode for free, and you can do both those things from the link below.
