I just watched the iPhone SDK event and it looked pretty awesome. I've long thought about the possibility of DS2 coming with accelerometer, but what Apple has done really blows me away. Here are some examples (they're developed for only 2 weeks for demo purpose): SPORE - http://youtube.com/watch?v=xkB6dOTB3IQ Touch Fighter - http://youtube.com/watch?v=jn83wizEMAw Super Monkey Ball - http://youtube.com/watch?v=4a6-cUOPoLY I guess there could be some amazing games for the iPhone. Imagine a car racing game where we can steer the iPhone as if we're driving the car. Put one finger on the right to accelerate, scroll your finger on the left to change the gear / view, etc. Or they can also make games like Nintendogs, Magical Starsign, or ZooKeeper with ease because they're all touch-based. But with added control, eg: pet your dog with 2 fingers, pinch him or shake your iPhone to beat your dog. I can't wait to see the games!! If they can built those demo games in 2 weeks, imagine what they can do in a real game development!
