Valve hired IceFrog, gave him unlimited resources, and he built the deepest competitive game on Earth.
Dota 2 is IceFrog's vision of DotA Allstars realized with Valve's resources and the Source engine behind it. Released in 2013 after an extended beta, it preserved the punishing complexity that defined the original: denying creeps, losing gold on death, Roshan timers, secret shops, and over 120 heroes with wildly different kits. Where League of Legends simplified the formula, Dota 2 embraced depth. The International, its annual world championship funded by community battle pass purchases, consistently offers the largest prize pools in esports history (over $40 million in 2021). The game rewards thousands of hours of learning and punishes you for every mistake.
Example
The International 2021 had a prize pool of $40,018,195, entirely crowdfunded through battle pass sales. First place took home over $18 million, making it the richest single esports event ever at the time.
Why it matters
Dota 2 proved that uncompromising complexity could sustain a massive competitive audience. Its crowdfunded prize pools reshaped esports economics, and its depth set the ceiling for what competitive multiplayer games could achieve.
