Inside the massive complex on the Las Vegas Strip that houses the glitzy Venetian casino and Sands convention centre, amid a soundscape of conflicting noises, thousands of players are mashing buttons while staring intently at flickering screens.
They're not playing slots or video poker. No, they're trying their hand at upcoming games such as Titanfall and Ryse.
This is the GameStop Expo. The world's largest video game retailer first organized the gathering of its most passionate customers last year during its annual meeting of store managers.
While the Electronic Entertainment Expo in Los Angeles is no longer open to the public, the GameStop Expo offers everyday gamers a chance to preview upcoming titles and hardware.
The expo's more than 5000 attendees waited in snaking lines inside a cavernous Sands Expo hall early Wednesday to test-drive Microsoft's Xbox One and Sony's PlayStation 4, the next-generation systems due out this November. Call of Duty: Ghosts, Titanfall, Ryse: Son of Rome and Battlefield 4 were among the most popular games on display.
