I'd rather see snowball throwing in it than speedskating or anything that requires you to mash buttons as quickly as possible or wave around your arm until you get an injury. These games used to fail because it was usually like this, with a less serious approach it could be much better. Doing snowball fights as in Ski Or Die with a Wiimote could be a lot of fun. Or even having it in a House of the Dead style, when you have to move through something on rail, but hit other things quickly enough in order not to get hammered yourself.
