Over the next four days, players, who previously qualified at regional competitions held across the globe, will be going for the gold in games like "Guitar Hero 5" and "Warcraft III."
The tournament-style matchups are occurring along rows of monitors erected in a giant circular pattern inside a dimly lit convention hall.
After the World Cyber Games launched in Seoul in 2001, the Grand Final has been held over the past 10 years in such cities as Singapore; San Francisco; Seattle; Monza, Italy; and Cologne, Germany. Last year, organizers said more than 82,000 spectators attended the event at the Century City New Convention and Exposition Center in Chengdu, China.
"We wanted to come back to America to celebrate our 10th anniversary because it's the most important market in terms of entertainment," said Hyoung Seok Kim, president of the World Cyber Games. "It's the center of entertainment. Many publishers and developers are located here, and there's a good infrastructure. We don't have to worry about translation."
