In game, although the avatars of the players talk using their mouths, it was all but a simulation of reality. In truth, everything is interpreted by reading brain waves. As such, the movement speed of players, the reaction rate, body movements, are all limited by the human mind. It all comes to the ability of the player to step outside the boundaries of cybergaming.
