On December 7th, Wave 3 of the Mario Kart 8 Deluxe: Booster Course Pack was released. This included 8 courses. My goal was to play as many of them as i could in an hour. Ultimately, i was only able to play 5 of the 8 in not too much longer than an hour.
London Loop was fun, the map looks intense and the level changes each lap so it's very interesting. Berlin Byways, like London Loop, has many famous places from the city as well as a course that also changes as you play. Peach Gardens is also interesting as on the last lap the direction of the race changes. I thought Merry Mountain was a little simple, but there are hazards on the track to watch out for. the same can be said, to a lesser degree, about Rock Rock Mountain as i found it to be more interesting with its flying sections and hazards.
Overall, i enjoyed the courses i played. i didn't pay for the DLC as it comes with my Nintendo Switch Online Expansion Pass.
