A new documentary, Second Skin, promises to reveal why people are so obsessed with massively multiplayer titles like World of Warcraft and Everquest, as well as even more pointless environments like Second Life. By capturing the online lives of seven devoted gamers, the film captures love, greed, addiction, and depression — all spurred by something that's not even real. Second Skin premieres at the South By Southwest film festival in Austin, Texas this March.
