Information storage medium and game system

1. A non-transitory computer-readable information storage medium storing a program that causes a computer to function as:

a character setting section that sets a plurality of characters selected by a player from among a plurality of characters possessed by the player to be battle characters;

a game processing section that executes a battle between the plurality of characters that have been set to be the battle characters and an enemy character that appears in a stage selected by the player, and determines whether or not the player has cleared the stage based on battle results; and

an information presentation section that, when a number of times that the player failed to clear the stage has reached a predetermined number:

extracts a plurality of characters that are recommended to be the battle characters from among the plurality of characters possessed by the player based on a parameter of each of the plurality of characters possessed by the player,

determines whether or not the player can clear the stage when the extracted characters are set to be the battle characters by comparing a parameter of the extracted characters with a parameter of the enemy character that appears in the stage that could not be cleared by the player the predetermined number of times, and

presents information that corresponds to a result of the determination to the player.

2. The information storage medium as defined in claim 1 ,

wherein the information presentation section presents information that suggests changing the characters that are set to be the battle characters to the player when the information presentation section has determined that the player can clear the stage.

3. The information storage medium as defined in claim 2 ,

wherein the information presentation section presents the information that suggests changing the characters that are set to be the battle characters to the player when the information presentation section has determined that the player can clear the stage, and the extracted characters do not coincide with the characters that have been set to be the battle characters.

4. The information storage medium as defined in claim 3 ,

wherein the information presentation section presents information that suggests that the player cannot clear the stage to the player when the information presentation section has determined that the player cannot clear the stage.

5. The information storage medium as defined in claim 2 ,

wherein the information presentation section presents information that suggests that the player cannot clear the stage to the player when the information presentation section has determined that the player cannot clear the stage.

6. The information storage medium as defined in claim 1 , wherein

the information presentation section presents information that suggests changing the characters that are set to be the battle characters to the player, when the information presentation section has determined that the player can clear the stage,

the information presentation section receives input from the player that changes the characters which are set to be the battle characters, as changed-battle-characters, and

the game processing section executes the battle between the changed-battle-characters and the enemy character in the stage, which is a same stage with a same enemy character which the player failed to clear the predetermined number of times.

7. The information storage medium as defined in claim 1 , wherein

the battle is part of a multi-stage battle game with successive stages of increasing difficulty level, in which a player is allowed to play a next stage with a higher difficulty level than a current stage only after the player clears the current stage by defeating the enemy character.

8. A game system comprising:

a character setting section that sets a plurality of characters selected by a player from among a plurality of characters possessed by the player to be battle characters;

a game processing section that executes a battle between the plurality of characters that have been set to be the battle characters and an enemy character that appears in a stage selected by the player, and determines whether or not the player has cleared the stage based on battle results; and

an information presentation section that, when a number of times that the player failed to clear the stage has reached a predetermined number:

extracts a plurality of characters that are recommended to be the battle characters from among the plurality of characters possessed by the player based on a parameter of each of the plurality of characters possessed by the player,

determines whether or not the player can clear the stage when the extracted characters are set to be the battle characters by comparing a parameter of the extracted characters and a parameter of the enemy character that appears in the stage that could not be cleared by the player the predetermined number of times, and

presents information that corresponds to a result of the determination to the player.

9. The game system as defined in claim 8 ,

wherein the information presentation section presents information that suggests changing the characters that are set to be the battle characters to the player when the information presentation section has determined that the player can clear the stage.

10. The game system as defined in claim 9 ,

wherein the information presentation section presents the information that suggests changing the characters that are set to be the battle characters to the player when the information presentation section has determined that the player can clear the stage, and the extracted characters do not coincide with the characters that have been set to be the battle characters.

11. The game system as defined in claim 10 ,

wherein the information presentation section presents information that suggests that the player cannot clear the stage to the player when the information presentation section has determined that the player cannot clear the stage.

12. The game system as defined in claim 9 ,

wherein the information presentation section presents information that suggests that the player cannot clear the stage to the player when the information presentation section has determined that the player cannot clear the stage.

13. The game system as defined in claim 8 , wherein

the information presentation section presents information that suggests changing the characters that are set to be the battle characters to the player, when the information presentation section has determined that the player can clear the stage,

the information presentation section receives input from the player that changes the characters which are set to be the battle characters, as changed-battle-characters, and

the game processing section executes the battle between the changed-battle-characters and the enemy character in the stage, which is a same stage and a same enemy character which the player failed to clear the predetermined number of times.

14. The game system as defined in claim 8 , wherein

the battle is part of a multi-stage battle game with successive stages of increasing difficulty level, in which a player is allowed to play a next stage with a higher difficulty level than a current stage only after the player clears the current stage by defeating the enemy character.
