Abstract: A music-oriented game machine with a feature to increase a feeling of competitiveness between players. Based on an evaluation of a performance of the first and second players based on their steps, the number of times step timing is presented as guidance is varied. Specifically, while reference arrows (46, 48) are displayed, a plurality of timing guidance arrows (50, 62) approaching the reference arrows (46, 48) are also displayed on a game screen image (40). As a result, guidance as to where step timing is arriving is shown to the player. Then, a speed at which the reference arrows (46, 48) approach the timing guidance arrows (50, 62), respectively, is changed from a default speed to speeds of half, twice, and three-times the default speed based on the result of evaluation on the respective player's stepping performances, to thereby change the guidance level.

Abstract: To output music other than original music, which is suitable to keep a player excited, in the place of a part of the original music, such as a beginning or ending thereof, which is unsuitable to serve as game music. When main part end timing TE arrives while outputting original music MO1, connection music MI2, correlated with original music MO2, which is next game music, begins playing.

Abstract: To increase a feeling of competitiveness between players of a music-oriented game. Based on evaluation of performance of the first and second players on their steps, the number of times step guidance is presented is varied. Specifically, while reference arrows 46, 48 are displayed, a plurality of timing guidance arrows 50, 62 approaching the reference arrows 46, 48 are also displayed on a game screen image 40, whereby a state of step timing gradually arriving is shown to the player. In addition, the number of timing guidance arrows 50 62, namely the number of times step guidance is presented to each player, is changed based on the result of evaluation on steps by each player.

Abstract: To evaluate a game playing performance from a new point of view, a control method for controlling a game machine allowing a player to enjoy stepping while listening to game music, comprises the steps of detecting whether or not the player puts their foot or feet on each of a plurality of step positions; judging, based on a detection result on the step position, according to which, of a plurality of pattern changes, a state of the player's feet relative to the plurality of step positions has changed to; calculating, based on the determined pattern change, an energy consumption amount due to a change of the state of the player's feet; calculating an accumulative energy consumption amount by accumulating an energy consumption amount calculated after a predetermined timing; and reporting the accumulative energy consumption amount calculated to the player.

Abstract: In addition to an optional game service in accordance with a designation made by a player, a compulsory game service not directly related to the designation by the player can be provided.

Abstract: A game-development control method divides a game scenario into an introductory part including at least one pre-event and a subsequent main part including at least one event correlated with the one pre-event. When each pre-event is generated in the introductory part, pre-event generation data generated based on the generation of each pre-event are recorded on a recording medium. When each event is generated, pre-event generation data correlated to each event are read among the pre-event generation data recorded in the recording medium, and the read pre-event generation data are reflected in the contents of each event.

Abstract: A similar polygon, which is larger than a basic polygon and has a similar shape to the basic polygon, is disposed to face the obverse surface of the basic polygon. A different texture from that of the basic polygon is pasted on the similar polygon. Then, a polygon image including the basic polygon and the similar polygon is displayed. When the polygon image is viewed from a certain viewpoint, the similar polygon is seen behind the basic polygon in a ring-like form, which serves as an edge of the basic polygon. As a result, a three-dimensional image using polygons can be provided with an edge.

Abstract: A game in which a player is prevented from applying an excessive force to a button on a pressure sensitive controller. For a game device comprising a controller 32 for supplying one of digital values in a predetermined range in accordance with the force pressing of a button, the predetermined range includes a response range in which at least some of the digital values smaller than a predetermined threshold fall, and a response limit range in which the digital value at the predetermined threshold or greater falls. When a digital value supplied from the controller 32 falls in the response range, a response image changing in accordance with a change in the digital value is displayed. On the other hand, when the value falls in the response limit range, a response limit image whose change in accordance with the digital value is limited is displayed.

Abstract: A method and a video game system that are capable of generating a field map with more natural geographical feature. The method and the video game system firstly divides the field map including a plurality of blocks into a first zone and a second zone by a boundary which consists of sides and comers in the blocks, then determines a first point for each side included in the boundary and a second point for each corner included in the boundary. Finally, the boundary is transformed into a more complex land shape by connecting the first points and the second points.

Abstract: A music game device is provided in which a player manipulates a manipulation unit in conformity with music. The device includes an input unit for setting play information including a plurality of tunes to be successively played and a play order of the plurality of tunes, a storage unit for collectively storing the play information, an automatic setting changing unit for automatically changing a part of the play information set by the player to a preset standard play information if the play information set by the player includes a setting which cannot be executed by the music game device, and a reproduction unit for successively reproducing the plurality of tunes in the play order based on the play information stored in the storage unit.
