Sega GT Online - Xbox

A blend of deep simulation detail and high-octane arcade action, Sega GT Online challenges gamers to qualify for licenses and earn money to soup up their rides and buy newer, more powerful cars. Players can then fine-tune nearly every aspect of their car's performance--from the muffler and brakes to the suspension, body weight and tires, before hitting the online racing circuit. Gamers even have the option to trade or bet their hard-earned cars and parts with other gamers before hitting more than a dozen devious, high-speed raceways. Of course, gamers can also talk trash as they take turns at 180 miles per hour with Xbox Live's voice chat capabilities.
