The first thing I got for the 3DS. Nice gameplay, 32 tracks (16 remastered from old consoles and 16 new ones) in 8 cups, 3 difficulty levels, 16 characters, and plenty of cars. However, it needed a few more wheels and gliders for variety. The graphics are also very nice.

Easter eggs:

For years, I only played on medium difficulty, but if you come first in the hardest difficulty, you unlock a character for each cup you come first in! That means from the initial 8 (Mario, Luigi, DK, Peach, etc.), an additional 8 less recognized characters are added (Daisy, Rosalina, Metal Mario, Shy Guy, etc.).

Apart from the various cars, wheels, and gliders, which you unlock randomly up to 5,000 coins, there are also golden car parts! Glider, wheels, and car! You unlock them by collecting 10,000, 15,000, and 20,000 coins respectively. They are like the default parts, but golden.

There is a mirror mode where you race the tracks backwards, unlocked when you come first in all cups, in all difficulty levels.
