Update: According to Microsoft, Minecraft has sold more than one million units globally on Xbox Live Arcade since its release five days ago.

Minecraft now holds the record for most Xbox Live day-one sales, snatching the title from Trials Evolution.

The Xbox 360 version of Minecraft became profitable within an hour of being offered for sale on XBLA, Mojang’s Markus Persson tweeted.

According to Persson, at the time of his post 400,000 people were playing the game.

The tweet caused confusion with Fez developers Polytron, who expressed amazement at Mojang’s access to such numbers.

"How did you get those stats from MS?" they asked via Twitter.

"We still don't know exactly how much Fez sold almost a month later. You get stats in 24 hours?”

"What? Really? I thought it was standard procedure! That sucks. :(" Persson replied.

"You're also getting free updates," said Polytron, "which is something every other developer on the platform is told is simply not an option."

"We had to fight for that, and we got a limited number of them. Not sure why they don't like it," came the reply.

In the end, it was deduced that the sales numbers were based on leaderboard participation, which Polytron called “a really inaccurate way to track sales”.

However, there was no bad blood between the developers.

“Congrats on a record-breaking launch!” Polytron tweeted, later adding “Minecraft did not get preferencial [sic] treatment regarding sale stats. just for the free updates!”, and “attention journalists: THIS IS NOT A SCANDAL”.
