  Also, the player character management unit 211 refers to the money acquisition table 423 to determine whether or not the virtual money acquisition condition is satisfied. If the virtual money acquisition condition is satisfied (step A19: YES), the virtual money associated with the acquisition condition determined to be satisfied is added to the virtual money held by the player as acquired (step A21). ), The acquired virtual money is notified by a screen display or the like (step A23).

Thereafter, the exchange rate changing unit 213 executes the changing process (step A25).
FIG. 14 is a flowchart for explaining the flow of the variation process. According to the figure, the exchange rate changing unit 213 refers to the exchange rate data 426 to determine the change flag. If the fluctuation flag is set to “1” (step B1: YES), it is determined whether or not the corresponding rate fluctuation end condition is satisfied with reference to the rate fluctuation condition table 427. If the end condition is satisfied (step B3: YES), the change of the rate is ended and the change flag is set to “0” (step B5).

On the other hand, if the fluctuation flag is set to “0” (step B1: NO), the exchange rate fluctuation unit 213 refers to the rate fluctuation condition table 427 and satisfies any rate fluctuation start condition. Determine whether or not. If satisfied (step B7: YES), the change rate is set to “1” by starting change of the exchange rate (step B9), and the exchange rate associated with the start condition determined to be satisfied. Is set to the variable exchange rate (step B11). Then, the changed exchange rate after the change is notified by screen display or the like (step B13).
When the above process is performed, the exchange rate changing unit 213 ends the changing process.

  When the variation process is completed, the game calculation unit 210 determines whether or not the exchange is reached (step A27: YES), the experience value / money exchange unit 212 executes the exchange process (step A29). ).

FIG. 15 is a flowchart for explaining the flow of the exchange process. According to the figure, the experience value / money exchange unit 212 determines whether or not a player exchange request is input from the operation input unit 100. If an exchange request is input (step C1: YES), the exchange rate data 426 is then referenced to determine the fluctuation flag. If the variation flag is set to “1” (step C3: YES), the experience value and the virtual money are exchanged at the variation exchange rate according to the player's request (step C5). On the other hand, if the change flag is set to “0” (step C3: NO), the experience value and virtual money are exchanged at the basic change rate according to the player's request (step C7).
When the above process is performed, the experience value / money exchange unit 212 ends the exchange process.

  When the exchange process is finished, the game calculation unit 210 determines whether or not the game is finished. If not finished (step A31: NO), the process returns to step A5. If the game is over (step A31: YES), the play time measurement is finished (step A33), and the game process is finished.

[Modification]
It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can of course be changed as appropriate without departing from the spirit of the present invention.

(A) Exchange of Level and Virtual Manate For example, in the above-described embodiment, the player character's experience value and virtual money are exchanged. However, the level and virtual money may be exchanged.

  Specifically, as shown in FIG. 17, for example, the level rise / fall 431a and the virtual money 431b to be exchanged are set in association with each other. When the player requests the exchange of the level and virtual money, the player character data 424 is referred to determine the level of the player character, and the level of the player character is increased / decreased based on the determined level. At the same time, the virtual money is reduced / increased.

  That is, when the level is exchanged for virtual money, the level of the player character is lowered to a level one level lower than the current level, and the virtual value of the player character is increased by the value of the virtual money associated with the lowering of the level. Increase money. For example, when the current level of the player character is “4”, the level is lowered to “3” and the virtual money is increased by “200 G”. On the other hand, when virtual money is exchanged for a level, the level of the player character is raised to a level one higher than the current level, and the virtual value of the player character is increased by the value of the virtual money associated with the increase in the level. Increase money. For example, when the current level of the player character is “2”, the level is increased to “3” and the virtual money is decreased by “100 G”.

  Further, in this case, the association between the level increase / decrease 431a and the virtual money 431b to be exchanged may be changed when a predetermined condition is satisfied. Specifically, as in the above-described embodiment, the set value of the virtual money 431b is uniformly set to, for example, 1 according to conditions such as the number of enemy characters defeated in battle, the number of game play times of the player, and the game play time. Change to 5 times or 0.5 times.

(B) Game to be applied Moreover, although the case where it applied to the role playing game was demonstrated in embodiment mentioned above, you may apply to another game. For example, in addition to fighting action games in which fight money, which is virtual money corresponding to wins or losses, is acquired as a result of the battle and the player's play level (stage) is increased, racing games such as cars and motorcycles, mahjong games and Go The present invention can also be applied to a game in which virtual money is acquired while the play level increases in accordance with game results such as success or failure or success or failure of a game, a shogi game, a puzzle game, or the like.
