I played Toad Harbor at the WiiU E3 event in 2013 in LA (Culver City actually where the demo was I went to) which I've yet to play again, but now that I've tried the current demo, I did Sunshine Airport, Electrodome and Sweet Sweet Canyon. I rather like the Canyon one. Electrodome is cool but I can't see them using it again in "Mario Kart 9" for a retro track tbh. And Sunshine Airport was actually slightly disappointing. As an aviation buff I was expecting more since an airport can be extensive, and the track was kinda small, it felt like an updated Coconut Mall, which I wasn't even a fan of until MK7. I HATED it on MKWii. but I'm not giving up on it cause the mall I played the demo at was loud and slightly distracting so maybe that was all
IGN's livestream lastnight shown the options for versus as: all items, shells only, bananas only, mushrooms only, bob-ombs only, no items, no items or coins and frantic. For anyone that was wondering before.
