eSports is so very in right now. Clearly all the Dota 2 kids are into it. This year's International (the game's largest annual tournament) has raised nearly $6.5 million for the prize pool from in-game player purchases. That makes it the biggest eSports prize pool of all-time by a wide margin, and with months of fundraising left before the finals.

The Hearthstone World Championship's $250,000 seems like small potatoes by comparison, but remember that whoever wins the $100,000 first place prize doesn't have to split it five ways.

That winner will be one of 16 finalists selected from four qualifier hubs around the world. 130 players each from the Americas, Europe, China, and Taiwan/Korea will be whittled down to just 16 finalists.
