Abstract: The present invention provides a game system 100, a game terminal 10, and a server device 40. Game system 100 allows players to play a game in a unit of a group constituting one game terminal 10 that has been selected as a parent node requiring a larger bandwidth during the game and at least two game terminals 10 that have been selected as child nodes requiring a smaller bandwidth during the game. The selection of the nodes is performed by server device 40. A parent node is selected from a game terminal 10 that has transmitted a grouping request containing ability data indicating that the terminal has the ability to be selected as a parent node.

Abstract: Provided is a game system capable of easily performing the second and subsequent matching processes of the game which is played in two or more rounds. The game system includes a center server and game machines that can be connected to the center server through a communication line, and executes a game played in rounds. In the game system, the center server performs matching on a predetermined number of game machines from the game machines in response to matching requests and gives the same session ID to the game machines which are matched first. Using the session ID, the matching is performed on each of the game machines to which the same session ID is given or on each of the game machines to which the same session ID is not given.

Abstract: The present invention provides a game system 100, a game terminal 10, and a server device 40. Game system 100 allows players to play a game in a unit of a group constituting one game terminal 10 that has been selected as a parent node and game terminals 10 that have been selected as child nodes. The parent node is capable of communicating with each node, and each child node is capable of communicating with the parent node. The selection of the parent node is performed by server device 40. A parent node is selected based on bandwidth notified from each game terminal 10.

Abstract: A CPU (511) of game device (50) generates bullet trajectory information when a bullet is fired at an opponent character by a player by operating a gun unit (56), and it transmits the bullet trajectory information to an echo server. The CPU (511), upon receiving the bullet trajectory information from the echo server, generates information showing a result of a determination as to whether the bullet has hit the opponent character based on the position information of a player character and the received bullet trajectory information. In a case in which a game device (50) is specified as the echo server, a game information set generated at game device (50) and a game information set received from an opponent game device are sent to opponent game devices (50) in an order in which game information sets are received.

Abstract: In a game system which may keep players interested in two or more games for a long time, a first game control server stores game result data transmitted from a first game device in a first data storing section. Then, the first game control server generates first usable data based on the newly stored game result data, and stores the first usable data in a data storing means of a first usable data transmitting section in which the first usable data are ready for transmission. Upon receipt of a transmission request command from a second game control server, the first game control server transmits the first usable data to the second game control server. Each player may execute a game program using the data obtained from a previously executed game and other usable data transmitted from a different game device.

Abstract: To provide a network game system for sharing, among a plurality of game machines, the positions and postures of objects associated with the game machines, while suppressing an increase in traffic in the communication network.

Abstract: To provide a network game system for enabling the player of a game to immediately find out, when a moving object, such as a bullet object or the like, contacts another object in a virtual space, from where the moving object came, by looking at the game screen image. Each of the game machines comprises a contact determination unit for determining whether or not the moving object contacts another object (402) placed in the virtual space; a contact direction acquisition unit for acquiring a contact direction of the moving object relative to the other object (402) when the contact determination unit determines that the moving object contacts the other object (402); and a contact image displaying unit for displaying an image (84) in accordance with a direction of a contact surface of the other object (402) and the contact direction at a position in the other object (402) in accordance with a contact position of the moving object.
