The second control unit 340 also adds information on the specified character selected by a player from among the specified characters displayed in this way (for example, as information on a helper) to the information on the team of this player.

The functions of the first control unit 330 and the second control unit 340 need not be separate, but may be realized together as a single function.

5. Configuration of Terminal Device 30

Next, the functions of the terminal device 30 realized by the components shown in FIG. 2 will be described with reference to FIG. 4. FIG. 4 is a block diagram showing the functions of the terminal device 30 according to an embodiment of the present invention. As shown in FIG. 4, the terminal device 30 includes mainly a storage unit 410, a communication unit 420, and a game playing unit 430.

The game playing unit 430 also adds a specified character selected by a local player from among the specified characters displayed in this way to local team (for example, as a helper).

6. Execution of “Service Providing Information on Other Players”

Next, how the terminal device 30 provides a “service providing information on other players” to a user will be described by citing a specific example.

FIG. 5 is a flow chart showing the operations performed between the terminal device 30 and the server device 10 in the case that a “service providing information on other players” is provided in a game system according to an embodiment of the present invention.

First, in step (hereafter called “ST”) 50, the player operates the terminal device 30 to start up the first application. Upon the first application starting up, the display device of the terminal device 30 displays the screen shown in FIG. 6. At this time, the terminal device 30 has not transmitted location information to the server device 10, and therefore, the screen shown in FIG. 6 does not show information on other players located within a predetermined distance from the location of the player.

In ST51, the player inputs an update command by clicking the icon 60 labeled “Update” displayed on the screen. Upon this, in ST52, a GPS receiver 36 in terminal device 30 receives location information indicating the current location of terminal device 30 from a GPS satellite. The terminal device 30 transmits the location information received in this way (for example, by the wireless communication processor 217 and the antenna 218) to the server device 10 through the communication unit 420.

In ST53, the first control unit (location information processor) 330 (realized, for example, by the control unit 112 or the like) of the server device 10 searches for other players located within a predetermined distance from the location of the player (the terminal device 30). An example of the processing executed in the first control unit 330 will be described with reference to Table 1.

TABLE 1
				Other players located	Players

				433333, . . . , B12122

The first control unit 330 stores the date and time of registration, the latitude and longitude, and information on other players located within a predetermined distance in the storage unit 310 correlated, for example, with player ID identifying each player. For example, to take the example of a player identified by the player ID of “A10001,” after receiving location information (latitude X001 and longitude Y001) from this player, the first control unit 330 stores the time of this information as “Jan. 1, 2016, 15:15.” The first control unit 330 then compares this location information with stored location information corresponding to other players, and searches for other players located within a predetermined distance for example, 10 km, 20 km, or 30 km) from the location of this player. The player ID of these other searched players are stored as “X12356,” “Y22313,” “Q23521,” “R11121,” . . . , “Z99212.”

In a first embodiment, for each player, the first control unit 330 can store only a predetermined number of players (for example, five) as other players located within a predetermined distance from the location of this player. The predetermined number of players may be randomly selected from among a plurality of players located within a predetermined distance from the location of this player. Instead of this, the predetermined number of players may be the five players having the most recently stored date and time of registration from among a plurality of players located within a predetermined distance from the location of this player.

Next, returning to FIG. 5, in ST53, the server device 10 transmits a list of players located nearby (the player ID of players located nearby) (and information on these players) to the terminal device 30.

In ST54, the terminal device 30 stores the list of players located nearby (the player ID of the players) received in this way in the storage unit 410. The terminal device 30 also displays the existence of these players, for example, on a display device as shown in FIG. 7. For simplicity, FIG. 7 shows the ID of the players located nearby, but may display the names (such as the user names) corresponding to these ID instead of the ID of the players.

The player may subsequently update such a list of players located nearby at any time (or, instead of this, at an arbitrary time after a predetermined time has elapsed from when the most recent update command was inputted). In this case, when the player, returning to ST51, again inputs an update command by clicking the update button 60, the same processing as described earlier is executed in ST52-ST54 to display an updated list (created by updating the information shown in Table 1) on the screen of the terminal device 30. At this time, as described earlier, a predetermined number (for example, five) of players is randomly selected from among a plurality of players located within a predetermined distance from the location of the player as described earlier. As a result, players who were on the list obtained by inputting the previous update command may be erased from the list obtained by inputting the new update command.

If the player does not wish to erase a specified player from the list, as shown in FIG. 7, the player may click this specified player (for example, the player identified by the player ID of “Y22313”) (setting “protection ON”) to protect this specified player from being erased from the list. The information on such protection is transmitted by the terminal device 30 to the server device 10, and the first control unit 330 in the server device 10 turns the information on protection corresponding to the specified player to ON (adds “Y22313” in the example of “Players to be protected” in Table 1). Therefore, if new location information is received for player “A10001,” for example, the first control unit 130 always leaves player “Y22313” among the plurality of players located within a predetermined distance. As a result, player “A10001” can continuously leave player “Y22313” among the players on the list of players located nearby on the display device of the terminal device 30.

In one embodiment, in the case that protection “ON” has been set for a given specified player, the protection “ON” set for this specified player may be set to protection “OFF” after a predetermined time limit (for example, 24 hours) has elapsed since the time when protection “ON” was set. As a device for realizing this feature, for example, the first control unit 330 stores the date and time that protection “ON” was set for each specified player for whom protection “ON” was set (the setting date and time) in storage unit 310 in advance, calculates the time elapsed from the difference between the current date and time and the setting date and time at a predetermined cycle for each specified player for whom protection “ON” was set in this way, and decides whether to cancel the protection “ON” by comparing this elapsed time with a predetermined time limit.

Other players who provide a character as a helper to the local team of a local player from the list generated for local player as described earlier in the “multiplayer game service” (described later) may be erased from this list promptly when the next update command is inputted or after a predetermined time has elapsed.

Next, returning to FIG. 5, in ST56, the player operates the terminal device 30 to end the first application.

7. Execution of “Multiplayer Game Service”

Next, how the terminal device 30 offers a “multiplayer game service” to the user will be described by citing a specific example.

FIG. 8 is a flow chart showing the operation performed between the terminal device 30 and the server device 10 in the case that a “multiplayer game service” is provided in a game system according to an embodiment of the present invention.

In ST60, the player operates the terminal device 30 to start up the second application.

In this second application, the player leads, for example, any team selected from among at least one team operated by the player and made up of a plurality of characters to play a game with an opponent character. During this game, any character from among a plurality of characters operated by a plurality of players located within a predetermined distance from the location of this player may be added (for example, as a helper) to the team so selected. The “plurality of players located within a predetermined distance” here are the players recognized through the “service providing information on other players” described earlier (for example, the players listed on the list of “people nearby” in FIG. 7).

How a character of another player is added to local team (as a helper) is indicated by the following ST61-ST64.

Specifically, first, the player inputs a search key in ST61. In the present embodiment, as an example, the player decides to set any leader character (leader monster) selected from among the leader characters (leader monsters) of at least one team operated by the player as the search key. For example, since the leader characters of each team operated by this player (for example, the five leader characters of monster A (red), monster B (blue), monster C (green), monster D (red), and monster E (blue) in FIG. 9) are displayed on the display device of the terminal device 30 as shown in FIG. 9, the player may decide to set any one from among these leader characters as the search key.

The communication unit 420 of the terminal device 30 transmits the search key decided by the player to the server device 10.

In ST62, a second processor (game playing unit) 340 in the server device 10 (realized, for example, by the control unit 112) uses the search key transmitted by the player to search the information stored in the storage unit 310 and thereby extract candidates for additional characters to be added (as a helper) to the team selected by this player.

A specific example of the information stored by the storage unit 310 for extracting candidates for such an additional character will be described with reference to the following Tables 2-4.

TABLE 2

	TM99999	CH91012, CH92001, . . . , CH93210	CH92009

As shown in Table 3, the storage unit 310 stores, for example, a character ID identifying each of the plurality of characters comprising each team correlated with the team ID identifying that team, and a leader ID indicating which character from among this plurality of characters is the leader character. Such information may be used to specify which characters comprise each team, and which character from among these characters is the leader character for that team.

As shown in Table 4, the storage unit 310 stores, for example, monster ID identifying which monster each character is, attribute ID identifying which attribute each character has (for example, red, green, blue, and yellow), and a character name which is the name assigned to each character, correlated with the character ID identifying that character. Such information may be used to specify which monster each character is, and which attribute each character has.

Returning to FIG. 8, in ST62, the second control unit 340 first specifies which players are the other players located within a predetermined distance from the location of the player is question, using, for example, the information shown in Table 1. Next, the second control unit 340 specifies which leader character each of the teams operated by these other players (or more preferably, the team used most recently in a “multiplayer game service” or the team listed first (that is, team 1) from among the plurality of teams operated by these other players) has, using, for example, the information shown in Tables 2 and 3. The second control unit 340 then specifies what type of monster each leader character specified in this way is and what attributes the monster has, using, for example, the information shown in Tables 3 and 4. Thereupon, the second control unit 340 determines the leader characters who share at least one of monster type or attribute with the leader character of the player in question (the leader characters selected by the player in question as the search key in ST61) from among the plurality of leader monsters specified in this way as candidates for additional characters. Finally, the second control unit 340 transmits character ID identifying the characters included among these candidates (and information on these ID) to the terminal device 30 as a “list of candidates for additional characters.”

In ST63, the game playing unit 430 (realized, for example, by the control unit 212) in the terminal device 30 displays the list of candidates for additional characters received from the server device 10 the display device of the terminal device 30 as shown in FIG. 10.

In ST64, the player clicks to select a desired additional character from among the candidates for additional characters shown on the display device of the terminal device 30. As a result, the communication unit 420 of the terminal device 30 transmits the character ID identifying this selected additional character to the server device 10.

In ST65, the second control unit (game playing unit) 340 of the server device 10 and the game playing unit 430 of the terminal device 30 collaborate to allow the new team obtained by adding the additional character selected by the player (in ST64) to the team selected by the payer (in ST60) to play a game with an opponent character. Such a multiplayer game has been disclosed, for example, by Japanese Unexamined Patent Publication No. 5755785 (hereinafter “Patent Document 2”) and is common knowledge, and therefore will not be described in detail. The entire contents of Patent Document 2 are hereby incorporated herein by reference.

Next, in ST66, the player operates the terminal device 30 to end the second application.

Thus, with the game system according to the present embodiment, during a multiplayer game against an opponent character by local team operated by a local player and made up of a plurality of characters, a multiplayer game service is provided in which an additional character to be added to local player as a helper is selected from among characters included in other teams operated by other players located within a predetermined distance from the location of local player, and a game is played against an opponent character by local team with the selected additional character added. As a result, each player is provided with a helper by a known player according to the current location of the player, and can find new enjoyment, not available previously, by playing a game against an opponent character by a team including this helper.

Making the character added to local team as a helper a character who shares at least one of monster type or attribute with the leader character of local team increases the total number of characters in local team who share at least one of monster type or attribute. As a result, each player can more usefully and effectively play a multiplayer game by local team against an opponent character.

Although a list of other players located within a predetermined distance from the location of local player (FIG. 5, ST53), a list of candidates for an additional character to be added as a helper to local team of local player (FIG. 8, ST62), and the like were described as being generated in the server device 10 in the foregoing embodiments, these lists may also be generated in the terminal device 30 using the same processing as in the server device 10.

In the foregoing embodiments, the plurality of other players located within a predetermined distance were displayed by a list of “people nearby” (FIG. 7). During this display, the user can select whether to receive a character provided as a helper from a player in question, and the display during the selection of a helper shown in FIG. 10 may be limited to only the players selected as described earlier. The time during which a helper can be selected may also be limited, and the list of helper candidates shown in FIG. 10 as a helper may be displayed only during this time.

Although using a leader character from among a plurality of characters comprising other teams of other players as an additional character to be added to local team of local player was described in the foregoing embodiments, a character selected from among a plurality of characters comprising other teams of other players according to various factors, including the attribute, type of monster, rank, or level, may be used as the additional character.
