This game is heavily biased towards certain tracks online. It always seems to finagle the same tracks.
>Peach Beach
>DK Pass
>Dino Dino Jungle
>Salty Salty Speedway
>Desert Hills

When you start noticing it it's actually insane. Play 5 races and move to a new room and you're guaranteed to keep repeating certain tracks
