Game system and computer-readable storage medium

Abstract

A game system includes: an image display device; an input device for outputting signals according to manipulation made by a user; and a control device for executing a fishing game in a virtual fishing spot with referring to the signals outputted from the input device, and for displaying images according to a progress of the fishing game on a screen of the display device. The control device includes: a size determining unit for determining a size of a virtual fish; a bite notifying unit for presenting a temporal change of an amount relating to a bite by a fish to the user to notify the bite to the user; and a change determining unit for determining at least one of a changing amount and a changing time period of the amount relating to the bite based on the size of the fish determined by the size determining unit.

What is claimed is:  
     
         1 . A game system comprising: 
 an image display device;    an input device for outputting signals according to manipulation made by a user; and    a control device for executing a fishing game in a virtual fishing spot with referring to the signals outputted from the input device, and for displaying images according to a progress of the fishing game on a screen of the display device, the control device comprising:    a size determining means for determining a size of a virtual fish;    a bite notifying means for presenting a temporal change of an amount relating to a bite by a fish to the user to notify the bite to the user; and    a change determining means for determining at least one of a changing amount and a changing time period of the amount relating to the bite based on the size of the fish determined by the size determining means.    
     
     
         2 . A game system according to    claim 1   , wherein the change determining means determines at least one of the changing amount and the changing time period of the amount relating to the bite such that the changing amount becomes larger and the changing time period becomes shorter as the size of the fish becomes larger.  
     
     
         3 . A game system according to    claim 1   , wherein the bite notifying means comprises a tension display means for displaying a tension value imposed on a virtual fishing line on the screen, wherein the amount relating to the bite comprises the tension value, and wherein the changing time period comprises a time period from a time when the tension value starts changing to a time when the tension value return to a value before the change.  
     
     
         4 . A game system according to    claim 1   , wherein the bite notifying means comprises a vibrator for applying vibration of a vibrating amount corresponding to the changing amount to the input device for a vibrating time period corresponding to the changing time period.  
     
     
         5 . A game system according to    claim 1   , further comprising: 
 a detecting means for detecting a manipulation of the input device by the user during the changing time period; and    a game executing means for executing the game on a condition that a fish is hooked if the detecting means detects the manipulation during the changing time period.    
     
     
         6 . A computer-readable storage medium for storing a game program for executing a fishing game in a virtual fishing spot with referring to signals outputted from an input device and for displaying images according to a progress of the fishing game on a screen of a display device, the program controls a computer to function as: 
 a size determining means for determining a size of a virtual fish;    a bite notifying means for presenting a temporal change of an amount relating to a bite by a fish to the user to notify the bite to the user; and    a change determining means for determining at least one of a changing amount and a changing time period of the amount relating to the bite based on the size of the fish determined by the size determining means.
