Patent ID: 8147305

Claim:
A game apparatus displaying a battle scene in which characters in a game world fight with each other, comprising: one or more first storage locations for storing one or more parameters for each enemy appearing in said game world; one or more second storage locations for storing, for a plurality of enemies, one or more operation timing patterns indicating the timing of one or more sequential player inputs to be input in association with a corresponding enemy, the operation timing patterns having different difficulty levels of operation, the different enemies having different operation timing patterns; input pattern changing programmed logic circuitry for displaying, when the battle scene is displayed, an input pattern stored for at least one enemy appearing in said battle scene and changing the display of said input pattern on the basis of one of the one or more operation timing patterns stored for the enemy appearing in said battle scene in said one or more second storage locations and on the basis of said difficulty levels; operation detecting programmed logic circuitry for detecting an operation by said player input in response to a change of said input pattern; changing value calculating programmed logic circuitry for calculating a changing value for changing the parameter of the enemy depending upon a degree of coincidence between the timing of the detected operation and the timing of the operation timing pattern; and parameter updating programmed logic circuitry for updating the parameter of the enemy appearing in said battle scene on the basis of the changing value calculated by said changing value calculating programmed logic circuitry.
