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 24 and we do the Lighting Cup 150cc and go through the credits and I give more of my opinions on the game! Enjoy and please remember to comment, like, and subscribe! Stay tuned for more 3DS vids and more! :)
