If you’re an old-school gamer geek like me you probably played and loved Super Mario Brothers 2. But the version that was released in the States is completely different from the Japanese version. Nintendo actually rebranded a game called Doki Doki Panic as a Mario game and released it in the U.S. In my opinion, it’s a much better game than the Japanese SMB2.
But don’t take my word for it. Check out both Doki Doki and Super Mario 2 (Japanese) at this location.
