I think I've got a love hate relationship with this game, and I'm not sure if me comparing it to Mario Kart is a good idea. As a remake it's incredible, when comparing between the original and the remake it's crazy to see how good it looks now. Minus the fact that it looks completely blurry on a Nintendo Switch but overall you can understand that it's a great remake.
I first decided to jump into adventure mode, this seemed like a great starting point where I could learn the ropes. There were three difficulties, easy, medium and hard. As I have played other kart racers in the past, I decided to jump into medium difficulty, this was a huge mistake. Beating adventure mode in medium was one of the most frustrating experiences, taking me hours to beat each race thanks to the steroid induced A.I. The A.I were also extremely predictable following the same paths each time, you could place traps in the same spot and they would just keep driving into them. The tracks were often really annoying and slow which would make the A.I even more painful to put up with. It's my fault really, I should have restarted on easy, but I was halfway through and couldn't be bothered to restart to change the difficulty. The boss fights were just cruel and annoying as well. Each boss was pretty much the same but they would all have a different trap shooting out their back. What made them insane was the fact that they were programmed to go insanely fast, faster than the player can actually go, if you overtook them they would instantly come flying past you. The puzzle levels I had no interest in playing due to them being extremely tedious and time consuming, I just couldn't be bothered to go back and get all the collectibles.
So would I recommend playing this? Kind of. If you want a more frustratingly hard kart racer, yes. Otherwise, just play more Mario Kart where the fun is at, at least there are people playing online there.
