You needn't worry about Dota 2 excitement diminishing: this year's International prize pool has managed to eclipse last year's by nearly $4 million. The total is currently sitting on a pretty $24,000,545, and while the International is currently playing out as we speak, players are still able to contribute to it via paying for battle passes.
It's pretty astonishing when you consider that, in 2012, the prize pool was an utterly poverty stricken $1.6 million. It's steadily increased since then, with last year's prize pool coming in at $20,770,460. Alright, I guess.
If you're keen to follow the excitement of The International but have a) never done so before or, b) don't even know what the hell it is, this exhaustive rundown should get you up to scratch.
