Just when you thought it couldn't get any more popular, the world's biggest League of Legends tournament is expected to sell out one of Asia's biggest indoor stadiums.

In an interview with Polygon, Riot Games' EVP of eSports, Dustin Beck admitted that the League of Legends 2014 World Championship is expected to sell out all 45,000 seats of Sangam Stadium in Seoul, South Korea. The stadium usually houses 65,000 seats, but due to Riot Games' changes to the stage and layout of the arena, sections adding up to 20,000 seats had to be removed to accommodate the event.

"We do expect to sell out," Beck said. "Our early ticket sales have all sold out. We're trying to create more capacity and flexibility, but so far so good."

Last year, the League of Legends World Championship sold out Los Angeles' Staples Center at 12,000 attendees. The event had 32 million viewers online and Riot Games expects even higher numbers this year.

The League of Legends 2014 will have smaller tournaments in Taipei, Singapore and Busan to determine the players in the World Finals on Oct. 19 at Seoul's Sangam Stadium.
