$2,019,002. That's the current prize pool for 2013's Dota 2 International tournament, which will be held this August in Seattle.
It's a massive payout — the biggest single-event prize pool in the history of competitive gaming — and it's only possible because of crowdfunding. See, Valve is selling Interactive Compendiums for their big event; for $US10 you get an interactive guide to the tournament, which Valve calls "the next best thing to being there," and $US2.50 of your contribution goes to the prize pool.
Dota 2, a multiplayer online battle arena game in which players pick heroes and fight in 5-on-5 team skirmishes for control of large battlefields, has become massively popular over the past two years — and it's not even out of beta yet.
