Despite being called Super Mario Word 2 in some countries, would be repositioned in the Yoshi series in the years following its release, but it's still a part of the Super Mario Advance series. Yoshi's Island: Super Mario Advance 3 is not technically a part of the Mario series. That does not take away the fact that the game provides some of the best Super Mario stages ever, though.
Unfortunately, Super Mario World: Super Mario Advance 2 has nothing new to offer for fans who've already played the original version. His play-style has also been slightly altered, and his jumps are much more similar to how they were in Super Mario Bros 2. The most notable of these changes is that there's no two-player mode, and Luigi is now an alternate character players can switch to anytime while on the world map. There are some minor gameplay changes, some of which were made in order to accommodate for the fact that it was now on different hardware. Released in 2002 in the US, this game is identical to its original counterpart on the Super Nintendo, except for the addition of some new story at the beginning and the end of the game.
While the original game might be a contender for being one of the best platformers of all time, Super Mario World: Super Mario Advance 2 is a lackluster entry in the Super Mario Advance series.
