Method for controlling server device, recording medium, server device, terminal device, and system

A non-transitory computer readable medium storing instructions which when executed by a processor cause to perform a method for associating a plurality of users of a battle, the battle being implemented a computer game in which the plurality of users battle against enemy characters, the plurality of users including users having never previously interacted in the computer game, the method comprising:

• transmitting data, over a computer network, for displaying the battle to terminal devices of each of the plurality of users;
• executing the battle and monitoring the battle, in response to receiving a request to proceed with the battle from the terminal devices of each of the plurality of users;
• and
• after the battle is over, selecting one or more participating users as candidate users by selecting from the plurality of users, using circuitry, one or more users who have participated in the battle and whose degree of contribution to the battle is larger than a threshold value, the degree of contribution including a number of attacks by each of the plurality of users.

A server for associating a plurality of users of a battle, the battle being implemented a computer game in which the plurality of users battle against enemy characters, the plurality of users including users having never previously interacted in the computer game, comprising:

• circuitry configured to
• transmit data, over a computer network, for displaying the battle to terminal devices of each of the plurality of users;
• execute the battle and monitoring the battle, in response to receiving a request to proceed with the battle from the terminal devices of each of the plurality of users;
• and
• after the battle is over, select one or more participating users as candidate users by selecting from the plurality of users, using circuitry, one or more candidate users who have participated in the battle and whose degree of contribution to the battle is larger than a threshold value, the degree of contribution including a number of attacks by each of the plurality of users.
