Winter!: Prepare for holiday gaming!
This game has you racing down tracks that look like ribbons, where the hills, curves, valleys, and obstacles are based on music you select. You control a vehicle of some kind, like a rocket car or something, switching lanes and either avoiding certain colors or collecting others. There are different game modes and rules you can choose from, but the overall effect is like being on a disco roller coaster. It's a really fun game, and a fun way to listen to music in a more interactive way. However, it gets a little repetitive after a while, and you kind of have to be in the mood for it.
