A game system includes operation units, a game processing unit that performs game processing on the basis of operation onto the operation units, a waveform information generator that generates vibration waveform information representing a vibration waveform corresponding to a first event that occurs in the game processing, and vibration units that vibrate on the basis of the vibration waveform information. In a case where the first event continues, the waveform information generator generates the vibration waveform information such that the amplitude of the vibration waveform decreases in accordance with the lapse of time.
