Share 'What's the best Video DG Game ?'

Two Christmas's ago I played DG on the TV, one of my nephews brought it.  It was very cool ... one of the courses was played in the mountains in the ice and snow.  It was a lot of fun. Problem being I'm no X boxx, EA, Wii guy and don't know what the platform may be or what the game software was ... anybody have any ideas?  Thanks
