“L3 takes place in virtual space, while the Go Game unfolds on actual city streets. But they share a common denominator: the widening of the game environment. Most forms of entertainment are defined by their edges: the outline of the Monopoly board or the dimensions of a movie screen. To enter the world of the game or the story, you enter a confined space, set off from the real world. Play-space doesn’t overlap with ordinary space. But Go and L3 don’t play by those rules. Go colonizes an entire city for its playing field; L3 colonizes the entire Web. These are games without frontiers.” Slate
