The prize pool for Valve's Dota 2 International has already exceeded $US6 million — $US6 million! — officially making it the largest tournament in gaming history. Well, really, it's been the largest tournament in gaming history for a while now. Last year's Dota 2 International was worth $US2.8 million, which until now was the biggest prize pool ever doled out in competitive video games.
This is all possible thanks to crowdfunding — anyone who buys a Dota 2 Compendiumfrom Valve contributes $US2.50 to the prize pool. There are also a whole bunch of stretch goals that open up new features in Dota 2, all of which have already been unlocked, because damn, $US6 million.
