Played a couple of the 50CC cups. its the beginner speed so its easy. It controls well and there's a really good feel and weight to the karts. The tracks are really fun with all the bendiness and route splits and are damn beautiful.
I've been a little skeptical because DD was praised by many and i thought it was trash but it seems like Nintendo really nailed this one.
Kind of crazy that in a couple of years, MK8 will be 10 years old. My guess is we'll be seeing either a whole new Mario Kart by then, or Nintendo has plans for more DLC, and this was sort of a test to see how DLC on a re-release does.
