With the Japanese version of Super Mario Bros. 2 being deemed too hardcore for Western players, Nintendo famously reskinned (and slightly retouched) Yume Kōjō: Doki Doki Panic into the lovely, successful, and formula-breaking Super Mario Bros. 2 for the NES we all know. And if you missed the original release, well, you can still grab the game via this Super Mario Bros 2 (NES) eBay auction.
It's the complete, boxed version you'll be bidding on, meaning you'll also be getting the slip case, box, manual, promotional insert, Nintendo Power poster, and plastic packaging. The game cartridge too, obviously.
