Server, control method therefor, computer-readable recording medium, and game system

A method of controlling a terminal device comprising:

• storing, as part of information related to a game, (i) information on plural kinds of player characters and at least one kind of enemy character associated with a predetermined battle event, (ii) information on a game content corresponding to the player characters, (iii) information on a first parameter value related to the battle for each of the player characters and/or each of the enemy characters, (iv) information on a second parameter value for each of the player characters and/or each of the game contents, and (v) information on a third parameter value for the predetermined battle event,
• causing a display processing unit to display a plurality of the game contents in a first field on a game image in the predetermined battle event;
• causing an input receiving unit to receive a selection of at least one desired game content to attack the enemy character from the plurality of the game content;
• causing a control unit to remove the game content selected by the player from the first field, update the first field with a new game content alternative to the removed game content, sequentially subtract the second parameter value of the selected game content from the third parameter value, and add a predetermined amount to the third parameter value at appropriate timing;
• and
• causing the display processing unit to display the corresponding first parameter value together with at least one of the player character and the enemy character on the second field of the display of the game,
• wherein the control unit enables selection of the new game content when the second parameter value of the new game content alternative to the removed game content is smaller than the third parameter value in which the second parameter value of the removed game content has been subtracted.

A non-transitory computer-readable recording medium that records a program causing the computer to perform steps of:

• storing, as part of information related to a game, (i) information on plural kinds of player characters and at least one kind of enemy character associated with a predetermined battle event, (ii) information on a game content corresponding to the player characters, (iii) information on a first parameter value related to the battle for each of the player characters and/or each of the enemy characters, (iv) information on a second parameter value for each of the player characters and/or each of the game contents, and (v) information on a third parameter value for the predetermined battle event,
• displaying a plurality of the game contents in a first field on a game image in the predetermined battle event;
• receiving a selection of at least one desired game content to attack the enemy character from the plurality of the game content;
• removing the game content selected by the player from the first field, updating the first field with a new game content alternative to the removed game content, sequentially subtracting the second parameter value of the selected game content from the third parameter value, and adding a predetermined amount to the third parameter value at appropriate timing;
• and
• displaying the corresponding first parameter value together with at least one of the player character and the enemy character on the second field of the display of the game,
• wherein a selection of the new game content is enabled when the second parameter value of the new game content alternative to the removed game content is smaller than the third parameter value in which the second parameter value of the removed game content has been subtracted.
