Video game device, character growth control method for video game and readable storage medium storing growth control program

A character growth control method for a video game in which an ability value of a main character is successively updated every time a speech/action is executed by successively executing contents of speeches/actions of a leader character, including training-related speeches/actions, to be given to the main character as an ability growth object and relating at least to training and a random factor according to consecutive operations of an operation unit, and causing the main character to perform the contents of the speeches/actions into which the random factor is incorporated, said method comprising the steps of:

• storing an enthusiasm parameter which is set to be a positive value corresponding to each of the training-related speeches/actions while being a negative value corresponding to any other speech/action is stored;
• adding a corresponding set value to a present enthusiasm parameter presently given to the main character every time the speech/action is executed;
• calculating a reliability degree between the main character and the leader character based on an execution result of the speech/action and the enthusiasm parameter value at that time;
• and
• judging a successful growth based on conditions if the ability value of the main character is equal to or above a specified level after the speeches/actions are executed a specified number of times and if the reliability degree given to the main character at the time of the judgment is equal to or above the specified level.
