God, don't make me depressed with my honest answer.
Wario's Shipyard was a bit of a reference of sorts to the first two Wario Land games,Has the Mario Kart series ever had any Wario Land references? I can't think of any, besides Wario's Car in Double Dash. If that's true, then probably none going by the past games.
Some minor Wario Land influence?? It's actually got obvious references, and for a track that still has to fit for Mario Kart 7, a lot of influence. :o Thanks for sharing, I didn't know about that!Wario's Shipyard was a bit of a reference of sorts to the first two Wario Land games,
The pirate theming, the music track having some minor Wario Land influence,
And a cameo of Bull Wario
