This is my Let's Play on the brand new Nintendo 3DS Game, Mario Kart 7. I will be covering all cups in 50cc, 100cc, and 150cc in this walkthrough and play in high quality HD! This is part 1 and we do the Mushroom Cup in 50cc and get used to the controls since this is my first time playing the game. Enjoy and please remember to comment, like, and subscribe! Stay tuned for more 3DS vids and more! :)
