Both Dan and I had a chance to jump in, and swat the balls. Yours truly playing with more strenuous actions to see how they effect the demo, the best example being in what Tsunoda referred to as a "power kick" once I'd done it, and yep, it sent the ball flying with much more force.
With all of that said, however, the first demo just still didn't feel like the goods. Which is why we switched pace and jumped right into a Natalised Burnout Paradise demo. The objective here was to simply jump in front of the camera, position your hands in the air as if holding a steering wheel and put your front foot slightly forward to accelerate.
Seriously, this was an incredible demonstration of the system's 1:1 movement tracking. Each time you shift your hands just a little to turn the steering wheel, it happens immediately on-screen and in-game, and stepping your foot back just a little will ease off the accelerator, while all the way back will slam on the breaks and if left there long enough, send you driving in reverse. Moreover, Tsunoda made a point to come out and walk around one of the players who was driving, waving his arms about to show off the fact the system would simply ignore him and leave the driver/player to continue to race, without distraction.
