Kids were bored after 2 days
Honestly most of the sports are just too hard to learn. The game my 10 year old liked the ice skating, which is like dance revolution but with your hands. But once she mastered it, she was all done with that. My six year old liked bobsled, which is like a driving game, but got bored with it pretty quickly. Even as an adult and knowing how to do most of sports personally, I found it to hard to learn which makes the games not fun.

Disapointing
I was expecting to get some more games in the spirit of Wii Sport but was rather disapointed by this game, as we didn't have much fun playing.
we have tried with the kids (age 10 and 8) the various winter sport and failed to get excited.

Hard work for a little fun
Love the graphics in this game! Really stunning the pre-event crowds and activities are fun to watch! The events take a lot of work to learn how to win. I make GREAT jumps on the ski jumps but crash every landing. The downhillls are fun and I'm great friends with the fence! Hate the figure skating - just doesn't make sense. The luge and bobsled are great fun. Can't figure out the curling enough to enjoy it. Given enough time and desire, I suppose I could learn to love this game. REALLY enjoy the games where I can use my Miis, tho!

Not for Beginners
Some aspects of this game are good: nice graphics, funny commentators, variety of games. However, if you are not adept at doing different things with each hand at the same time, it can be frustrating. The motions needed for turning/steering are very, very subtle and sometimes pretty intricate, so there is a steep learning curve. In some events, you need to use the controller and do one motion with your right hand, and then use the nunchuck with a different motion in your left. For kids with lots of video experience, this may be part of the fun, but for younger kids (or us adults), even the beginner settings can be too difficult. We don't play it much.

absolutely love it
Absolutely awesome!!!! I can't ski fast, or jump long, and the commentators keep saying I should have stayed in bed, but it is so great anyway - I just tell them "shut up" or "I'm trying." It's pretty hilarious. The graphics are amazing. Love the luge and skeleton. Figure skating is tricky, requires grace and precision, so no surprise there. Unbelievably real, feel the speed. Thankful, though, that when I crash into the fences or fall off the jump, I'm not actually breaking any bones! Want to keep playing because I really think I might learn to win one day.
