Apple has posted a new feature on Second Life to the games area of its Web site. “Second Life isn’t a game so much as it’s a tool for building anything you want: vehicles, avatars, clothes, buildings, funky sculptures. You can even build your own games and host them inside the world, pulling in other players to participate. You own everything you create in the game, including the land you purchase for your buildings, and can sell it for real world money. Welcome to your second life.”
