Where else can you fight a man named Pizza Pasta?!

But honestly, the Punch-Out!! arcade game is more of a novelty. Very cool in concept, it plays well, but other than presentation it was made better by ever subsequent port. Still a great game on its own, but it is one of those odd times where the home port was an improvement over the arcade original.
But if you've never played it and you find one in the wild I still absolutely recommend giving it a shot. The double screen set up is just so cool on the "aww it really was a different time" kind of way.
