Network game system and program

A non-transitory computer-readable medium including a program that is executable by a server apparatus, the non-transitory computer-readable medium causing the server apparatus to function as:

• a client group manager that receives a request from each of a plurality of client apparatuses for joining a client group through a predetermined network, that authenticates each of the plurality of client apparatuses, and that provides authentication information to each of the plurality of client apparatuses for joining the client group through the predetermined network;
• a connection state manager that manages a connection state of each of the plurality of client apparatuses;
• a game progress state manager that manages a progress state of a network game in each of the plurality of client apparatuses;
• an execution client designator that designates a first optional client apparatus from among the plurality of client apparatuses belonging to the client group as an execution client for executing a predetermined processing among processing for a progress of the network game, and gives notice of a first designation of the execution client to the first optional client apparatus through the predetermined network;
• a management client designator that designates a second optional client apparatus from among the plurality of client apparatuses belonging to the client group as a management client for exchanging game progress information regarding the progress of the network game in the client group, and gives notice of a second designation of the management client to the second optional client apparatus through the predetermined network;
• a game progress information receiver that receives the game progress information in the client group from the management client designated by the management client designator;
• a game progress state updater that, on the basis of the game progress information received by the game progress information receiver, updates the progress state of the network game in each of the plurality of client apparatuses being managed by the game progress state manager;
• and
• a disconnection determiner that determines whether communication with at least the first optional client apparatus designated as the execution client from among the plurality of client apparatuses belonging to the client group is disconnected,
• wherein the execution client designator changes the first optional client apparatus that is designated as the execution client from among the plurality of client apparatuses belonging to the client group every predetermined period,
• wherein the server apparatus is connected to the client group through the predetermined network,
• wherein the server apparatus manages the network game and does not play the network game, and receives information necessary for the progress of the network game from the client group from only the management client from among the plurality of client apparatuses belonging to the client group, and
• wherein, when the disconnection determiner determines that the communication with the first optional client apparatus designated as the execution client is disconnected, the execution client designator designates another client apparatus belonging to the client group as the execution client.

A non-transitory computer-readable medium including a program that is executable by a computer apparatus, the non-transitory computer-readable medium causing the computer apparatus to function as:

• a client group joiner that requests a server apparatus for authentication for joining a client group through a predetermined network, and that receives authentication information from the server apparatus for joining the client group through the predetermined network;
• an input accepter that accepts a predetermined input for a progress of a network game from an input by an operation of a player;
• a predetermined processing executer that, when the computer apparatus is designated by the server apparatus as an execution computer apparatus for executing a predetermined processing from among processing for the progress of the network game, executes the predetermined processing on the basis of a first notice from the server apparatus;
• a within-group transceiver that transmits and receives game input information based on the input accepted by the input accepter and game execution information regarding execution of the predetermined processing by the predetermined processing executer within the client group through the predetermined network;
• and
• an outside-group transmitter that, when the computer apparatus is designated by the server apparatus as a management computer apparatus for exchanging game progress information regarding the progress of the network game in the client group with the server apparatus, transmits the game input information with respect to the client group and the game execution information to the server apparatus on the basis of a second notice from the server apparatus,
• wherein the computer apparatus is connected to the client group through the predetermined network and the predetermined network is connected to the server apparatus,
• wherein the computer apparatus plays the network game with client apparatuses of the client group through the predetermined network and does not play the network game with the server apparatus,
• wherein the within-group transceiver does not transmit and receive the game input information to and from the server apparatus, and
• wherein the outside-group transmitter only exchanges the progress of the network game with the server apparatus when the computer apparatus is designated as the management computer apparatus.
