Server system and method for controlling computer system

A method, implemented on a server, for controlling a computer system that asynchronously controls a process of a game played by each player on external devices, the method comprising:

• at the server,
• changing a parameter of a first player when a given activation condition has been satisfied, the activation condition being a condition whereby a process that changes the parameter of the first player is performed;
• performing an extension control process that changes a parameter of a second player who relates to the first player when the second player has logged in after the activation condition has been satisfied;
• receiving, over a communication section of the server, from the external device, an indication that the second player loss in;
• and
• responsive to receipt of the indication that the second player logs in, adjusting a change width of the parameter of the second player that is changed by the extension control process corresponding to an elapsed time until the second player logs in after the activation condition has been satisfied.

A network game system, the network game system comprising external player devices and a server system that is connected to the external player devices via a communication network, the server system asynchronously controls a process of a game played by each player on the external player devices, the server system comprising:

• at least one microprocessor;
• and
• a communication section that communicates with an external player device;
• the at least one microprocessor is configured to
• change, by a parameter change control section, a parameter of a first player on a first external player device when a given activation condition has been satisfied, the activation condition being a condition whereby a process that changes the parameter of the first player is performed, and transmit the parameter that was changed to the first external player device;
• perform, by an extension control section, an extension control process that changes a parameter of a second player who relates to the first player when the second player has logged in on a second external player device after the activation condition has been satisfied;
• receive, over the communication section from the second external player device, an indication that the second played logs in;
• and
• adjust, by a change width adjustment section, responsive to receipt of the indication that the second player logs in, a change width of the parameter of the second player that is changed by the extension control process corresponding to an elapsed time until the second player logs in after the activation condition has been satisfied, and transmit the parameter that with the adjusted change width to the second external player device.
