All the racers have been blasted into space! Now they can race in Galaxies from the Super Mario Galaxy games. Tracks from the first Galaxy game are selected from the Comet Observatory and tracks from Starship Mario. Not every galaxy appears in the game but most of them do.
Playing the game is just like any other Mario Kart game. Gliders reappear and propellers for underwater courses. Launch Stars will also let you travel to different parts of the galaxy.
All the items from the other game in the Mario Kart series appear with some new items.
Most of the characters from previous Mario Kart games appear. There are some new ones and unlockable ones. Characters from other series also appear
