I always liked The twilight princess boss fight on the bridge against king bulbo (or whatever his name was), i loved the style and riding on horse back and also the location.
Becuase it MARIOkart and MARIO party, they use only mario based characters. If it was Nintendo kart or something like that then yes, zelda characters and other nintendo characters would be in it.
I dont really like the water temples and here's why:
The oot one had me troubled for ever, but now its not so hard
I hated everything about the MM one
I loved the TP one but i still wasnt a fan of the layout of the temple
They always just confuse me and are pretty hard
