#4 – Doki Doki Brothers
The game that us western gamers grew up with as Super Mario Bros 2 really was not a Mario game at all! The good people of Japan got a totally different Super Mario Bros 2. A game that would not make it over to us westerners until it was released as part of the Super Mario All Stars Collection on the Super Nintendo years later. The reason for this was because Nintendo felt the original Super Mario Bros 2 was too hard for us.
So what the hell did we get? Well the game we got was originally called Doki Doki Panic. But they re-designed many of the sprites to make the game look like it always was a Super Mario game. Super Mario Bros 2 is sometimes seen as the red headed step child of the Mario series despite being a really fun game in its own right.
