I decided to replay the base game's tracks since I've been playing the booster course pass for the first time this year. I do think that Mario Kart 8 can be a bit boring sometimes since there isn't much incentive to come back to it as much as Double Dash, but there is no denying that Nintendo put a lot of effort into the tracks of this game. It was fun on Wii U, and it's still very fun now.
