If you like Olympic games then you might find something in here for you. But like all games of this genre not all is ok. What i love about Olympic style games are there short intensive mini-game stylings. With ESPN winter version there is not the same intensity as mashing the 100m (especially in multiplayer) in the summer versions of this style of game.

Ski Jump - works fine and once you master the controls you realise it is over simplified.
Downhill/Slalom - tough. good luck winning medals here.

Speed Skating - probably the most enjoyable and the most reminisant of multiplayer side by side action.
Bobsled - tough but some fun to be had.
Curling is just plain boring. Good for your collection if you're bored. Gets extra marks cause i scored mine cheap and i generally like this style of game. I love the multiplayer minigame aspect & constantly trying to beat my personal bests....
