What sets Go! Sports Ski apart from many of the other recent titles is fairly robust online multiplayer support. The game has several different online gameplay modes, including time trials, battle runs and slaloms -- as well as the ability to download the ghosts of the top players in the world. Once you've downloaded the ghosts you can either watch them for tips or compete directly with them in the single-player game. It's a nice little inclusion and I hope that Sony starts offering this level of online multiplayer support for all of their upcoming PSN titles.
Go! Sports Ski's real hook though is that it is controlled exclusively by the Sixaxis motion controls. Yes, like Lair and Super Rub-a-Dub, you control your character entirely via tilting the controller around -- the surprising thing is that it actually works pretty darn well. To move your skier forward, you tilt the controller forward. To turn your character to the right, you tilt the controller to the right. To do a sharp turn, you tilt the controller in the direction you want to turn and tilt it back at the same time. To jump, you simply jump the controller up quickly. While there is a bit of a learning curve (like all motion controlled games), it only takes a couple runs to get comfortable with the controls -- and once you do, you'll be surprised at the precision that is possible with it.
