2. Description of the Related Art Conventionally, there is a game such as a role playing game (RPG) that takes a very long time from the start to the end of the game. In this type of game, a save function is usually provided so that the game can be advanced while the play history is stored in the middle. Many of such games require the player to fulfill some save conditions, such as staying at an inn in the game space or using save items, in order to execute the save function.

[0003]

However, when playing a game such as RPG in a portable device which has been rapidly developed in recent years, particularly a battery-powered portable game device, the remaining battery power becomes too small. In some cases, it is impossible to proceed further without saving. In such a case, even if the battery is replaced, the play history data that has not been saved is lost. Therefore, the time and effort spent by the player on the game until the battery runs out is wasted, and this is one of the factors that lowers the appeal of the game in the portable game device.

In order to solve this problem, there is a method in which the game can always be saved. However, in such a case, a new problem arises in that the game characteristics are reduced and it is difficult to enhance the appeal of the game.

Next, FIG. 4 shows a case where the RPG is played on the portable game device 100 having such a configuration.
It is a flowchart which shows the save environment generation processing example. The display unit 22 (FIG. 2) in the case where the processing of FIG.
1A to 1C and FIGS. 6A and 6B, and FIG. 5 shows a basic image display example. 2 and 3 in the following description.
Is referred to as appropriate.

The inn A shown in FIG. 5 is an inn displayed in a normal state, and the inns B and C are temporary inns displayed only in a predetermined case.

The RPG exemplified here is a game system in which a player plays while viewing a game screen on which a player character operated by the player himself is displayed, and also has game history data (for example, current experience value information of the player character,
It is set so that the player character can play while saving the current level information, the acquired item information, the current position information, the appearance character information, the cleared game stage information, the play time information, and the like of the player character. In this RPG, as shown in FIG. 5, game stages such as towns 320, 330, and 340 and a mountain of Devil 350 are scattered in the wilderness, and players are provided in the town 320 and the like. Inn (not shown) or Inn A in the wilderness
The game history data can be saved by moving the player character 310 operated by oneself to C. For the movement of the player character 310,
The direction key 18 is used. Furthermore, during the movement of the player character 310 in the wilderness, the monster as the enemy character is set to appear randomly. If the player character dies after fighting the enemy character, the game is over without waiting for the ending. As described above, when the game is over during the game, or when the power of the portable game device 100 is turned off during the game, the saved game history data is read out to read the saved game history data. The game can be restarted midway under the same conditions as those recorded in the game history data.

In FIG. 4, at the time of start, FIG.
As shown in (A), inn A is displayed in the wilderness in game space 300 (S1).

Next, it is determined whether or not the remaining battery level is 80% or less (S2). If the remaining battery level is 80% or less (S2: Y
ES) and the inn B are newly displayed (S3). At this point, the display unit 22 displays an image as shown in FIG.

Thereafter, it is determined whether or not the remaining battery power is 50% or less (S5). As a result of the determination, the remaining battery power is 50
% Or less (S5: YES), the inn C is newly displayed (S5), and the process proceeds to the next step. At this point, an image as shown in FIG. 1C is displayed on the display unit 22. As a result, at the time of proceeding to S6, FIG.
As shown in (C), the inn A and the temporary inns B and C are all displayed on the display unit 22. In addition, it is preferable that the inns B and C are displayed so that the inn is a temporary inn at a glance.

The battery is further reduced, and the remaining battery power is 20%
If it is below (S6: YES), the player character 3
A selection screen is displayed from which the user can select whether or not to warp the inn from the current position (S7). At this time, a message window 312 is opened on the display unit 22 as shown in FIG. 6A, and the message "The battery level is low. Warp to the inn now? → Yes / No"
Message is displayed. And the player
By moving the cursor to either “Yes” or “No” with the direction keys 18 and pressing the operation button 12,
You can make a selection. Here, if "Yes" is selected, it is determined that the player wants to warp to the inn (S8: YES), and the processing section 210 moves the player character 310 to the inn instantly (S8).
9). On the other hand, if "No" is selected, the process directly proceeds to the determination of S10 without performing the warping process (S8: NO).

It should be noted that the inn that is the warp destination in S9 is the inn that is closest to the current position among the places where the player character 310 has passed in the past, and this reduces the game quality. It is preferable for prevention.

When the remaining battery power is further reduced to 10% or less (S10: YES), it is first determined whether or not a predetermined time has elapsed since the previous save (S11). In this case (S11: YES), the game history data is forcibly saved (S12). At this time, an image as shown in FIG. 6B is displayed on the display unit 22. On the other hand, if it is determined in S11 that the predetermined time has not elapsed (S11: NO), the process ends without performing forced save. It should be noted that the predetermined time in S11 is set in advance based on a reasonable time that is assumed to be severe for the player when the game history data is lost.

As described above, in this embodiment, the remaining battery level is detected, and a process for generating a save environment required for saving is performed based on the detection result. As a result, it is possible to save even if the game cannot be saved normally, and it is easy to prevent the game history data from being lost due to running out of battery. In addition, a plurality of save environments having different contents can be generated stepwise according to the detected remaining battery level.

Further, before the remaining battery power reaches 10%, the player can determine whether or not to save, so that the game quality is maintained.

In particular, in the present embodiment, as the save environment, an environment with reduced difficulty for satisfying the save condition of "the player character reaches the inn" is generated, and the save condition request itself is maintained. Therefore, a decrease in game characteristics is prevented.

Here, as a means for reducing the degree of difficulty, the appearance rate of the inns A to C as save points is increased, so that the player character 310 is moved to one of the inns A to C before the battery runs out. It becomes easy to do. On the other hand, since the movement of the player character 310 to the inns A to C itself must be performed by the player, the game characteristics are maintained. Furthermore, since an inn, which is originally present in the game space, is used, the player does not feel discomfort due to the occurrence of the save environment. In addition, the increase in the encounter rate with the inn makes it possible for the player to make diligent saves and to be cautious of preparing for a dead battery or game over.

When the remaining battery power is further reduced, the player character 310 can be warped to the inn, so that it is possible to prevent the battery from running out during the movement. In the present embodiment, the warp is particularly effective in reliably reaching the inn within a small amount of time left because there is a high risk of encountering a monster while traveling in the wilderness. It is to be noted that the decision of whether or not to warp is left to the player, so that the player's intention is respected and the game characteristics are maintained.

When the remaining battery power becomes 10% or less, forced saving is performed, so that loss of game history data due to running out of battery can be reliably prevented. As a result, the player is protected from losing game history data due to a cause outside the game space such as a battery exhaustion. Then, when the remaining battery level is relatively large, and when a predetermined time has not elapsed since the previous save, the forced save is not performed, so that a decrease in game characteristics is prevented.

Since the game device itself has the remaining amount detecting means, it is not necessary to use a complicated program for detecting the remaining battery amount. For this reason, information for remaining amount detection stored in the remaining amount detection information storage unit 228 and the information storage medium 240 can be created relatively easily. As a result, the development cost of the game software to be used can be kept low, and the selling price of the portable game device 100 or the information storage medium 240 can be set low.

FIG. 7 shows a portable game device 1 of the present embodiment.
20 is a flowchart illustrating another example of a save environment generation process when performing RPG using 00. As a premise of FIG. 7, this RPG is set so that the game character can save the game history data by using a save item that enables the save in the game space.

In FIG. 7, when the remaining battery power becomes 20% or less (S20: YES), a save environment in which one more save item exists in the game space than usual is generated (S21). The one more save item may be displayed near the player character together with a glittering mark, for example, or may be forcibly given to the player character.

FIG. 8 is a diagram showing an example of image display when a save item is forcibly given to a player character. In FIG. 8, reference numeral 310 denotes a player character, and 320 denotes a save character that appears only in a save environment. Then, the save item 330 is handed to the player character 310 along with a message from the save character 320 indicating that the battery is almost exhausted and suggesting a save.

FIG. 9 is a flowchart showing an example of processing when saving game history data using the save item 330. FIG. 10 shows an image display example corresponding to the flowchart of FIG.

In FIG. 9, first, as shown in FIG. 10, an item window 340 for displaying all items currently owned by the player character 310 is displayed (S30). The item window 340 is displayed when the player operates the operation buttons 10, 12, 14, 16, the direction key 18, and the like in a predetermined procedure.
It is displayed according to the process of 0. Next, by selecting a save item (“book of save” in FIG. 10) from the items displayed in the item window 340 (S31: YES), save of the game history data is executed. (S32).

As described above, in the present embodiment, the appearance rate of save items in the game space increases when the remaining battery power reaches a predetermined level. Therefore, even when the player character does not have a save item, the save item can be quickly obtained and the game history data can be stored before the battery runs out. Further, since the player has to perform the operation of obtaining and using the save item itself, the game characteristics are maintained. Furthermore, since the save items, which are originally present in the game space, are used, the player does not feel uncomfortable due to the occurrence of the save environment. Rather, it is possible to contribute to the improvement of the game property by increasing the opportunities for acquiring items.

Also, since the save item is displayed on the screen, the player can easily notice the appearance of the save item. For this reason, when the remaining battery power is low, the game history data can be saved by quickly acquiring and using the save item. In particular, when a save item is forcibly given to the player character, the player does not overlook the save item that has appeared. For this reason, it is possible to more reliably store the game history data. Also, by displaying a message when a save item is given, the player can know that the remaining battery level is low, and can prepare for running out of the battery. Further, since the save items are exchanged on the screen, it is possible to add visual fun to the game.

The embodiment of the present invention is not limited to the above-described example, and various modifications are possible.

For example, in FIG. 4, S10 and S11
May be omitted. In this case, the player is ultimately responsible for saving the game history data,
This becomes a risk, and the game characteristics are surely maintained.
Further, the save point may take a form other than the inn, or the save condition may include that the save execution is selected in addition to the arrival at the save point. Or,
A save environment in which the appearance rate of enemy characters is reduced can be generated as a save environment with reduced difficulty for satisfying the save condition.

The game that can generate a save environment based on the remaining battery power is not limited to RPG. For example,
A save environment can be generated in a sports game such as a volleyball game, a soccer game, a baseball game, a tennis game, and a racing game. Specifically, for example, in the case of a sports game in which a save can be performed only at the time, when the number of times per game is determined, the number of times that can be performed is limited only when the remaining battery power is low. You can do much.
When the number of times is not limited, it is conceivable that the time execution process is forcibly performed when the remaining battery power is low. In the case of a racing game, a save relay point that does not normally exist may appear on the course, or a save relay point that originally exists may appear before the original position. .
