the number of the game contents which are counted at the time of modifying has a predetermined value, and

the circuitry is configured to modify the predetermined value on the basis of prescribed conditions.

2. The computer according to claim 1 , wherein the circuitry is configured to increase, for each of the first game contents, the parameter value of each of the first game contents based on the counted number of the game contents whose type matches each type of the first game contents, when the counted number of the game contents reaches a predetermined value.

3. The computer according to claim 1 , wherein the circuitry is configured to output display data corresponding to the parameter value of each of the first game contents based on the counted number of the game contents whose type matches each type of the first game contents.

4. The computer according to claim 1 , wherein the circuitry is configured to control the display to display, for each of the first game contents, an image based on display data corresponding to a predetermined value.

5. The computer according to claim 1 , wherein

the first game content forms a deck used in an event which occurs in the game, and

the circuitry is configured to output display data for displaying a deck editing screen for prompting the player to select the first game contents for forming the deck.

6. The computer according to claim 5 , wherein

the circuitry is configured to:

output display data for displaying a deck selection screen for prompting the player to select a deck to be edited from a plurality of decks; and

when the deck is selected at the deck selection screen, output display data for displaying the deck editing screen relating to the selected deck.

7. The computer according to claim 1 , wherein the circuitry is configured to output display data for displaying the parameter value of each of the first game contents before the number of the game contents is counted.

8. The computer according to claim 1 , wherein

the parameter value includes attack power value,

the memory is configured to store, for each player, identification information and name of the player, the plurality of game contents, and the plurality of first game contents, and stores for each of the first game contents, identification information and a type of the first game contents, modified attack power value, rarity value, and health point value, and

the circuitry is configured to extract the plurality of first game contents of the player from the memory, extract the modified attack power value and health point value of the extracted first game contents, and execute progress of the game by using the extracted first game contents, the extracted modified attack power value and extracted health point value.

9. The computer according to claim 8 , wherein

the memory is configured to store identification information, name, attack power value, and health point value of an enemy character, and

the circuitry is configured to execute progress of the game by reducing the health point value of the enemy character based on the modified attack power value of the first game content, and by reducing the point value of the first game content based on the attack power value of the enemy character.

10. The computer according to claim 1 , wherein the circuitry is configured to:

extract identification information of each of the first game contents and identification information of each of the plurality of game contents,

extract a type of each of the extracted first game contents based on the extracted identification information of each of the first game contents,

extract a type of each of the extracted game contents based on the extracted identification information of each of the game contents,

count, for each of the extracted first game contents, a number of the extracted game contents whose extracted type matches each extracted type of the first game contents, and

modify, for each of the extracted first game contents, the parameter value of each of the extracted first game contents based on the counted number of the extracted game contents whose type matches each type of the extracted first game contents.

11. The computer according to claim 1 , wherein the predetermined value is an upper limit value.

12. A non-transitory computer-readable recording medium having recorded thereon a program for a computer including a memory configured to store a plurality of game contents associated with a player and a plurality of first game contents selected from the plurality of game contents associated with the player according to an instruction from the player, the computer executing progress of a game by using a game content having a parameter value, the program causing the computer to execute a process, the process comprising:

counting, for each of the first game contents, a number of the game contents in the plurality of game contents whose type matches each type of the first game contents;

modifying, for at least one of the first game contents, the parameter value of each of the first game contents based on the counted number of the game contents whose type matches each type of the first game contents;

executing progress of the game by using the plurality of first game contents; and

controlling a display to display, for each of the first game contents, an image indicating the counted number of each of the first game contents, wherein

the number of the game contents which are counted at the time of modifying has a predetermined value, and

the process comprises modifying the predetermined value on the basis of prescribed conditions.

13. A method for controlling a computer for executing progress of a game by using a game content having a parameter value, the method comprising:

storing, in a memory, a plurality of game contents associated with a player and a plurality of first game contents selected from the plurality of game contents associated with the player according to an instruction from the player;

counting, using circuitry, for each of the first game contents, a number of the game contents in the plurality of game contents whose type matches each type of the first game contents;

modifying, for at least one of the first game contents, the parameter value of each of the first game contents based on the counted number of the game contents whose type matches each type of the first game contents;

executing progress of the game by using the plurality of first game contents; and

controlling a display to display, for each of the first game contents, an image indicating the counted number of each of the first game contents, wherein

the number of the game contents which are counted at the time of modifying has a predetermined value, and
