It's not a game entirely without merit. The presentation is strong, balancing the Olympic spirit with the charm of the Mario and Sonic casts. The Dream Events offer a nifty Mario Kart-esque experience in some colourful and nostalgic environments, and the ice hockey is quite enjoyable. Elsewhere however, the gameplay is overly dull. Sports like snowboarding should have been a treat to play, but they're slow and awkward.
But it's not the game's fault that curling and figure skating aren't the most riveting sports to translate to video games, right? If grenade hockey and unicorn ice joust were official Winter Olympic sports this game would have been awesome. But they're not, so it isn't.
