Whether or not you pay for GameStop's annual membership plan, the planet's largest video game retailer is opening the doors of the Las Vegas Sands Expo and Convention Center to the public for its annual GameStop Expo this August, which this year features hands-on opportunities with both the Xbox One and PlayStation 4. For a $35 general admission ticket, you'll get access to both consoles on August 28th -- long before their respective holiday launches -- as well as a chance to play a variety of upcoming games. Should you shell out a stone cold $90, you'll snag a copy of Madden NFL 25 for Xbox 360, gain early entry to the show (one hour) and "access to panel discussions with some of the biggest names in the industry." Per usual, attendees must be older than 17, and the event's a one-day affair. But then you'll be in Vegas, so... maybe stay for a few days.
