I voted for Sand Kingdom, Lake Kingdom, Seaside Kingdom, and Metro Kingdom
The only one I truly enjoyed and appreciated was the Sand Kingdom or Tostarena. Seaside Kingdom was a looker, pretty good too. Metro Kingdom was fun. Lake Kingdom was okay. The rest I didn't really care for much. I was expecting a lot more from Super Mario Odyssey. I guess I'm comparing it to Super Mario 64 too much and holding it to that unbeatable quality? Because I can really beat that game down with criticisms despite having enjoying it a lot. It didn't have that classic Mario feel to it overall, despite paying homage to pretty much Mario everything within the game
