An information processing system having a processing circuitry that determines whether a predetermined start condition including consumption of a predetermined game medium is met, automatically realizes a predetermined advancement of a game part with a first attribute associated with one user when it is determined that the predetermined start condition is met, determines a setting value of a first parameter based on a consumed amount of the predetermined game medium or a consumed type of the predetermined game medium, the first parameter being related to advancement of the game part with the first attribute, starts to count the first parameter to be updated toward the determined setting value of the first parameter, when it is determined that the predetermined start condition is met, and allows a termination result of the predetermined advancement to be output, when an updated counting value of the first parameter meets a predetermined output condition, the termination result of the predetermined advancement being determined based on the updated counting value of the first parameter or on the setting value of the first parameter as determined.
