Immersion is a bunch of biatches. I wouldn't pay them a dime. I can make a rumble controller in my freaking garage and I'd have to pay them money if it was used on a video game system? The other pussy thing they say is that a controller can't be coded to recieve rumble unless they get paid too. When their patent has nothing to do with software code at all. Fortunately by next round we may see controllers not using force feed back for rumble and using a different technology.
