14. New Super Mario Bros. 2 (Nintendo 3DS)
One of two new platformers for Mario in 2012, this brought improved visuals and new challenges to Mario. The theme of more coins then ever before certainly made for a new play experience, but it arguably wasn't the step up for the series some expected. This title also brought about the dawn of download content for Mario, which displeased some as the stand alone adventure isn't Marios longest, especially when compared to the lengthy classics like Mario World or Galaxy 2.
13. Super Mario Bros. 2 (SNES)
Its the game that didn't start life as a Mario title (In Japan it was released minus Mario as Doki Doki Panic before later being re-released as Super Mario USA) and is sometimes not viewed with the same regard as its 2D brothers. That doesn't take away from the fact its still an immensely enjoyable experience. The game was later seen as strong enough to be Mario's Game Boy Advance debut. That version was based on the SNES Mario All-stars version, with a few additional improvements to make for its best version to date.
