Hi,
First of all, nice to see so many of you excited about CBNK (here and around the web). We at Polarbit have high hopes for iPhone / iPod Touch as gaming platforms and feel extremely lucky to be a part of this from the very beginning.
A few comments:
At present, there really isn't any better way to control racing games on the iPhone than the gyro / tilt. The primary benefit is of course the "analogue" precision: tilt a little, turn a little - tilt a lot, turn a lot. Also, we can use screen taps for other commands - like jumping of firing weapons - that do not require analogue precision.
We've seen some creative solutions with steering wheels and stuff as part of the HUD, but you'll never achieve the same smoothness of controls with this method. Plus, you're gonna lose the "full-screen" feeling of the iPhones fabulous display.
For those of you worried about loosing you're street cred by playing a wacky game that requires tilting the phone in public, don't worry - it's more discreet than you think. You can play and still look cool.
As for Raging Thunder, if you find it too tough in portrait, you'll get a chance to experience the game in landscape mode with a few added bells and whistles soon enough.
Cheers,
Tommy
