Wow, these tracks look so amazing! I have watched a few of the videos posted by GameXplain with their analysis, and the amount of authentic work that went into the background as well as the track designs is absurd... Particularly in Big Blue, Wild Woods and Ribbon Road; the amount of detail is just mind-blowing!
It'll be neat to see the Villager joining in, the Villagers have been confirmed as being the same weight as Mario / Luigi?
I'm also quite excited for that subway track, it's just excellent how Nintendo is always able to take such simple concepts and make them complex and fascinating.
I'm still not a fan of Neo Bowser City, and I really don't see that opinion changing no matter what, but I suppose I can give props for the rain effect being refined.
Dry Bowser, from a few sources, has been confirmed to be in the heaviest class. It's not surprising overall, but I suppose you never know. There are instances of oddities throughout the game, such as Donkey Kong being lighter than Wario, among others. The radiating lava that can be seen between the crevices of his shell upon performing stunts is quite a nice touch in my opinion.
200cc is nice I guess, but I'd be lying if I didn't say I'm dreading having to do all of the cups over again in 200cc, lol.
