Server device, method for controlling the same, computer-readable recording medium and game system

A method for controlling a server device that provides a game, in which a plurality of players can participate, and that is connected to terminal devices operated by the players via a communication line, the server device comprising an information storage unit, and a control unit that accesses the information storage unit to perform processing to display an image of the game at the terminal devices, the method comprising:

• accessing the information storage unit to store information on a group fighting event of the game involving at least a first group and a second group,
• operating the control unit to perform processing to provide a group fighting event such that the first group, the second group, and one or more participants who do not belong to a group that is engaged in the group fighting event participate in the group fighting event, wherein the group fighting event further includes at least one watcher who does not fight during at least one portion of the group fighting event;
• during the group fighting event, receiving a selection of a plurality of game media from a random set of game media;
• determining if the plurality of game media satisfies at least one criterion in the set of:
• a type match, an attribute match, a degree of rareness match, or a combination match;
• and
• when the plurality of game media satisfies the at least one criterion, activating an effect for a battle phase of the group fighting event.

A non-transitory recording medium that provides a game, in which a plurality of players can participate, that is connected to terminal devices operated by the players via a communication line, and that can access an information storage unit that stores information on a group fighting event of the game involving at least a first group and a second group, the recording medium having stored thereon a computer program to configure the computer to:

• access the information storage unit to store information on a group fighting event of the game involving at least a first group and a second group,
• operate the control unit to perform processing to provide a group fighting event such that the first group, the second group, and one or more participants who do not belong to a group that is engaged in the group fighting event participate in the group fighting event, wherein the group fighting event further includes at least one watcher who does not fight during at least one portion of the group fighting event;
• during the group fighting event, receive a selection of a plurality of game media from a random set of game media;
• determine if the plurality of game media satisfies at least one criterion in the set of:
• a type match, an attribute match, a degree of rareness match, or a combination match;
• and
• when the plurality of game media satisfies the at least one criterion, activate an effect for a battle phase of the group fighting event.
