I think the advantage of this is that it feels like you're in the game more than you would not using a vibration option. It really does make a difference in my opinion. Explosions, crashes, attacks, and jumps to the ground usually all have the vibration in it, and they make me more drawn to gaming as a result.
Your thoughts on vibration in video games? Has this been done before the N64 and PS1 on a console that I didn't mention?
