9. Tubular - Super Mario World (SNES)
http://www.youtube.com/watch?v=hSXSWqUirGA "Tubular" is like a personal invitation from Nintendo to challenge their authority. It exists purely to increase the likelihood that you'll smash up your SNES controller and have to replace it with a brand new one. Super Mario World is arguably Nintendo's finest achievement to date and probably the best Mario game ever made, but "Tubular" is one of the most annoying levels the great company ever put out into the world. Not only is timing absolutely everything here, but the sheer amount of dodging that the level requires borders on the abusive. Many have tried for years and failed. One look and you'll know exactly why this level is considered a scourged of the retro platforming genre.
