Developer Sidhe Entertainment's GripShift is not so much a driving game as it is a puzzle game that happens to use cars as its focal point. It's got far more in common mechanically with something like the PC cult favorite TrackMania than any brand of racer, arcade or otherwise. Unfortunately, GripShift's unique qualities are undermined by one severe flaw: Driving in the game isn't much fun. Even though you're not racing, you still have to drive a vehicle around the game's plentiful number of tracks (or puzzles, or whatever you want to call them), and the controls for doing so are so frustratingly unwieldy that it renders the entire process an infuriating chore. It's too bad, really, as the concept of a platform-heavy puzzler that features crazy cars sounds like a neat idea. GripShift just doesn't deliver on its lofty concept.
