Abstract: A game device includes a processor implementing a character process that performs a character control process; a game process that performs a game parameter calculation process; and a display process that displays a game image based on results of the game process. The processor implements the character process that performs a process that controls a master character that is operated by a player, and a process that controls a plurality of subordinate characters that are subordinate to the master character. The processor implements the game process that performs a process regarding a game event that involves a first subordinate character and a second subordinate character based on a first relationship parameter between the first subordinate character and the second subordinate character, a second relationship parameter between the master character and the first subordinate character, and a third relationship parameter between the master character and the second subordinate character.

Abstract: When a game situation has satisfied a participation situation condition, a posting site is accessed, and a message that includes participation URL address for another person to participate in the game is automatically posted to the posting site. Another person can participate in the game played by the player by accessing the participation URL address included in the message. A participating character that has been automatically generated appears in the game played by the player. A game screen that shows the state of the game in which the other person participates is displayed on a terminal of the other person.
