This review will not be a critical assessment of "Mario Kart 8" as a whole. I've already written a review for the Wii U version of the game, which you can read if you head over to my profile. Rather, this review will be discussing how the Nintendo Switch port of "Mario Kart 8," also known as "Mario Kart 8 Deluxe," stacks up against the Wii U version. Is it worth it? Yes, absolutely.
"Mario Kart 8 Deluxe" features a few solid differences from the Wii U version, notably 1080p graphics, the ability to hold two items, brand new characters, a highly revamped (and much needed) Battle Mode, new features to help beginners out, and a lot more! Nintendo really took things into account with this one, working to make sure it wasn't just a lazy "port" of the game, and their effort shows!
So, should you buy it? Well, if you don't already own the Wii U version, buy this new "Deluxe" edition NOW!!!!! However, if you own the Wii U version, it depends on how the revamps to Battle Mode (along with the new characters) sound to you. Like 'em? Go get it! Not interested? Just stick to the Wii U version. Regardless of your system of choice, "Mario Kart 8" is an absolutely amazing game and everyone should have it in their collection, regardless of whether they own a Switch or a Wii U.
Final rating: 10 out of 10 "Fantastic"
