Very good Mario Kart

Unquestionably the best Mario Kart, with circuits "gravitational" to make your head spin (Mario Circuit). It's very beautiful, very fun, and online works great with many people.
Concerning the 16 new tracks, it's perfect but uneven. Some circuits lack originality, while the vast majority remain very fun. Special mention for music (Champidrome, Mario Circuit, Arc en Ciel Route), really fabulous.
Regarding the 16 circuits "retro" then there fabulous. They are beautiful, with quite a makeover and gravitational portions (Circuit DK) added for extra chilli. But (there is a "but") certain circuits are bland (eg desert) and we would have preferred other more funs circuits.
Special mention to the Arc road retro heaven, totally modernized with excellent music!
So great game, very fun and addictive, but with 5-6 somewhat bland circuits. Perhaps a future DLC (and free) for other cuts and thus new channels?
Game obviously recommend, pending Super Smash Bros., Xenoblade Chronicles, Bayonetta 2 or The Legend of Zelda! That heavy!
