When the announcement was first made my mind immediately went to one thing: a Mario Galaxy version of Space Fantasy with maybe a different layout since it would have the advantage of a new building. The music would be amazing to hear during a roller coaster ride through space. Now listen to this and imagine waiting in line for a Mario Galaxy ride. Not including opening fanfare, just the slow part.
But I guess Universal Creative wanted to avoid a retread of something they've already done and I can respect that. Mario Kart sounds promising.
