There is considerable variation and negotiation over the relationship between video game developers and tournament organizers and broadcasters. While the original "StarCraft" events emerged in South Korea largely independently of Blizzard, the company decided to require organizers and broadcasters to authorize events featuring the sequel "StarCraft II". In the short term, this led to a deadlock with the Korean e-Sports Association. An agreement was reached in 2012. Blizzard requires authorization for tournaments with more than US$10,000 in prizes. Riot Games offers in-game rewards to authorized tournaments.
