I play single player FPS games exclusively. Years ago I got addicted to a Microsoft controller called Sidewinder Dual Strike. IMHO, it is the gold standard for FPS game controllers and if it will control a FPS game well it will control any game well. Getting used to it was it's downfall. The DS is no longer usable under W7 and so I'm looking elsewhere. When forced to use a K/B & M I revert to a Kensington trackball which I find infinitely superior to any mouse. For years I have been hoping that some game controller maker would recognize the benefits of the old DS or at least a trackball. If I were designing this controller I would put a trackball under the right thumb instead of the touchpad. Also, I see nothing wrong with the left stick of Xbox 360 controller and look forward to comparing it to this controllers left pad. I hope Steam isn't changing things just to be different. If at all possible I'd like Steam to write their drivers to include DS support. I don't think it would be difficult as the DS simply emulates the K/B & M.
