Alternate reality gaming is not a new idea. The concept mixing fantasy elements into a game played in this world has been happening for years. It's been attempted in videogames many times with mixed results. A memorable failure was Majestic, the online alternate reality game that should have taken off like a rocket, what with is complex mystery that used multiple mediums to create a layer of reality over the real one. Tarver Games' upcoming Ghosts Attack is keeping in that spirit. Using Google Maps within the iPhone, the game sets up a veil of reality over the one you currently occupy.
