If it were used to play game sounds, yeah, that’s stupid. It’s just the vibration motors with software controls that can replay the same vibrations of a sound file. They are not high enough quality to be used for game audio. They are good enough to play a wakeup/shutdown sound (optional), or other things that just add bonuses to the controller. It’s free, assuming your haptics were good enough.
