I had my reservations about the PlayStation Move, but I held my final judgment until I actually got my hands on it. The same goes for the Microsoft Kinect, though watching videos of press actually playing games on the hardware have me an even greater mixture of excited and dubious than with its Sony counterpart; while the Move seems like a natural progression within the line of the Wii’s play style, the Kinect, if you haven’t heard, doesn’t have any motherf’ing controllers.
And while I don’t think Sonic Free Riders will effectively be the system-seller like Wii Sports was for the Wii or Sports Champions is trying to be for the Move, I think if this game works, it will be a much greater boon for the Kinect than Kinect Adventures or Kinectimals (both links appear to be broken since the Xbox.com redesign yesterday). For it to sense you leaning to varying degrees, jump, spin, and whatnot is much more impressive than taking your body into a binary input for couched/not crouched or verbally abusing virtual animals, but since this is a marketing tool, this trailer should be taken with a grain of salt.
To get a better feel for how it actually feels to play the game, watch Giant Bomb‘s Ryan Davis free ride his way through a demo of the game with Sega’s David Allen. If you’re saying that the swimming bit seems the most uninspired, then you are correct! Hope remains, though, for the rest of the game. I am, however, somewhat of an optimist.
