It turns out Minecraft has become something of a phenomenon. According to Gamesindustry.biz, the little sandbox building zombie game that could, did; netting the game's creator and only developer at the moment, Markus 'Notch' Persson, some US$350,000 a day. That's more than $3.5 million overall with some 278,772 copies sold in the Alpha dev stage alone.

The report says he'd been in meetings with both Valve and Bungie, but has not announced any new partnerships, instead opting to invest his hefty cash-reserve into creating his own dev studio.

"Most my time these days is taken up by meetings and lawyers, accountants, banks, potential partners, potential employees, and the occasional interview," he wrote on his blog. "All this non-development work will result in a much nicer working environment, with talented people helping out with development, an actual office, and a much better way to deal with support issues, bug reports and feature requests."
