This is the first time I got beaten to the punch with a video topic by a YouTuber who's videos I watch, guess that's what happens when I sit on a finished script for 5 months. Actually I finished this a few days before the second wave of the Mario Kart 8 Booster Pass got announced. Not gonna say I caused that but I will say you're welcome.

Oh also because I forgot to say in the video, if I don't mention any specific piece of background music then just assume I said I liked it because this game has one of my favourite OSTs.
