Very very very good Mario Kart. Fun alone or 4, online or at home: Mario Kart 8 is a game that justifies the purchase of the console itself. My children 3 and 4 years of good times pass over (even if they finish mostly with a lap down) and also really fun, either locally or with friends online (for Mario Kart is a true racing game when it leans a little seriously)
In the end everyone is benefiting, it is a tour de force that succeeded with this Nintendo game whose graphics are gorgeous.
