Game system, game processing method, computer-readable non-transitory storage medium having stored therein game program, and game apparatus

A game processing method for controlling a computer of a game system for performing game processing including a versus game in which a match-up of a player against an opponent is held, the game processing method comprising:

• performing a versus game process against the opponent;
• storing rating data indicating skill of the player at the game relative to opponents;
• determining a variation amount of the rating data for the player based on a score of the player and a score of the opponent in the versus game;
• in response to a determination that the player has lost, decreasing the rating data for the player by the variation amount without increasing the rating data for the opponent;
• updating the rating data based on a win/loss result of the player in the versus game;
• determining whether the rating data satisfies a predetermined condition;
• changing a parameter associated with an object in the versus game in response to a determination that the predetermined condition has been satisfied;
• and
• generating, for display to the player, an image of the object in which the changed parameter is reflected.

A non-transitory computer-readable storage medium having stored therein a game program executed by a computer of a game system for performing game processing including a versus game in which a match-up of a player against an opponent is held, the game program causing the computer to at least execute:

• performing a versus game process against the opponent;
• storing rating data indicating skill of the player at the game relative to opponents;
• determining a variation amount of the rating data for the player based on a score of the player and a score of the opponent in the versus game;
• in response to a determination that the player has lost, decreasing the rating data for the player by the variation amount without increasing the rating data for the opponent;
• updating the rating data based on a win/loss result of the player in the versus game;
• determining whether the rating data satisfies a predetermined condition;
• changing a parameter associated with an object in the versus game in response to a determination that the predetermined condition has been satisfied;
• and
• generating, for display to the player, an image of the object in which the changed parameter is reflected.
