Check this out! The Iceland developers behind Eve Online, CCP, put forth this supposed in-game demo at Game Developer’s Conference 2007. They plan to allow Eve pilots out of their ships, as full body avatars, and enter the space stations to meet, make battle plans (and hopefully drink alien liquor and look cool). I know I am a massive nerd, but I can’t wait!
