Fans watch the opening ceremony at the League of Legends Season 3 World Championship final between South Korea's SK Telecom T1 and China's Royal Club in October 2013 at the Staples Center in Los Angeles. The event sold out in less than a day. While video game tournaments have been sellouts in other countries, most notably South Korea, the Staples Center event last year brought professional gaming more into the American mainstream.
