Microsoft is gearing up for another big update to Xbox Live, and soon they'll be offering a friend of a friend feature that will allow users to peruse their friends' friend lists. It's a voluntary service, and is gated by your age to avoid any parental fears. If you'd rather turn it off ahead of time, they already have a dedicated site set up for that purpose. (Gamertag login required.) That update will be dropping on December 4th. Relatedly, they're also rolling out a whole bunch of new backwards compatability options for your old Xbox games. Highlights include support for: Baldurs Gate: Dark Alliance, Burnout 2: Point of Impact, Forgotten Realms: Demon Stone, Indiana Jones And The Emperors Tomb, Star Wars: Jedi Starfighter, Syberia II, The Bard's Tale, Worms 3D. There's also support for a slew of sports titles going all the way back to 2003.
