I finished Super Mario Odyssey! Here is me in Peaches Kingdom.
The game was excellent and worthy of all the praise it has in reviews online. I think my favourite kingdoms were the Luncheon Kingdom and Lost Kingdom. They were just beautifully designed worlds with just enough challenge to be stimulated but not too frustrated.
I think I now somewhat understand the appeal of other 3D Mario games like Super Mario 64 and Super Mario Galaxy and would like to play these one day.
