There's a lot of action taking place at the Amway Center this weekend, but all of it is digital. More than 100 professional gamers are competing in Orlando Aug. 9-13 for the Call of Duty World League Championship — an event that has an attendance rate of up to 5,000 people a day. The Amway Center was transformed into an e-sports arena filled with giant screens to show the action from competitors playing the war simulator game Call of Duty.
