Method for performing derivative scenario in a video game program

摘要

Disclosed is a method for performing a derivative scenario in a game program operated on a home television game machine, has the steps of: generating the derivative scenario on the basis of a step in the game program; and performing the derivative scenario on the basis of real time proceeded by a first timer means with which a main body or an external storage device of the home television game machine is provided; wherein the derivative scenario is defined to be performed in the process of a relative time and the relative time is related to the real time so that the derivative scenario is performed in the process of the real time.
