Patent attributes
When support appeal reception information is received from a player terminal, a support appeal information transmitter transmits support appeal information for support appeal to other player terminals than the player terminal. In this case, the other player terminals are positioned within a predetermined range from the current position of the player terminal. In the case where support contents information indicating support contents is received from any of the other player terminals in accordance with the support appeal indicated by the support appeal information, a support appeal reply execution information transmitter transmits support appeal reply instruction execution information for instructing the player terminal to execute the support contents indicated by the received support contents information to the player terminal. The player terminal then executes support from the other player terminals in the executing event on the basis of the received support appeal reply instruction execution information.
