Looks like someone took a look at Mario Kart 7 and said, "We can do that too!" So now S&ASRT will have air and water modes to go with the land racing. But besides the derived-feeling nature of this change, the game itself looks gorgeous and I'm happy to see even more SEGA characters and environments of yore revived.
