It's a joy to play. The animation, character designs, voice acting, music, visual style and detail, cinematics and everything else are all fantastic. Even the motion controls. I would have liked to have subtitles for the dialog, especially to translate the non-English-speakers' taunting and speeches, if it's even half as hilarious as the things the English-speaking opponents say. "Ya doon't got cheeseburgers in those glooves, have ya Mac!?!?!?!" "I like raw fi-yish."
As for Mario, Captain Jim and I call the referee that--not in the sense that he is run-jump-fireball yah-wah-yahoo! Mario, but as if he is simply a man named Mario.
I wish I had the game. Grnnnngh...
