In 1991, Super Mario World was the pack in game when you bought the SNES and it was a great game. So to everyone's surprise, Nintendo announced it was making the sequel to it and in 1995 it was released on the SNES. Not only was it one of the best games for that console, it also was a sequel superior to the original and also very different. It sold very well and went on to be a solid entry in the Super Mario Bros series.
