This certificate is good for a 2-hour birthday party from Rolling Video Games. What is a mobile video game theater? FOUR widescreen high-def TVs cover the walls in front of 16 Ultimate Game Chairs with built-in vibration motors synched to the on-screen action with speakers in each headrest. Everything is linked, so 16 players can play the same game -- or against each other! Play as a team and enjoy different games, because there are plenty to choose from -- all the newest games from Wii, Playstation 3 and Xbox 360 with a "Game Coach" to help anyone who needs it. Since there are no single-player games, it's the ultimate party for a group to have fun together at birthday parties, events, festivals and more! Expires 7/16/11. www.RollingVideoGames.com
