Force Feedback...better known to some as rumbling is done by i think a small ocilator....which spins and different rates. Most games.....most notably on consoles such as the n64 use rumble features such as when the player does something or gets hit.....it would be neat for graal especially if you could use npcs to direct it. For example, you could have your controller rumble if you were a bomy that hit against a wall when swimming.....
