It's ungodly short, beatable in an hour tops, and Mario's physics feel all kinds of off, but there's a certain unique charm to the portly plumber's portable debut. Helmed by Gunpei Yokoi, it definitely sticks out from the rest of the series with its unique setting and quirks, and an insanely catchy soundtrack to boot. You've got next to nothing to risk by giving it a try, so go do it.
