The Reverse Design series looks at all of the design decisions that went into classic video games. This is the third installment in the Reverse Design series, looking at Super Mario World. Written in a readable format, it is broken down into ten sections examining some of the most important topics to the game: 1. The specific level design patterns within Super Mario World that make it such a successful and classic game; 2. Evolutions in the smallest mechanics of the Mario games that give the player more control and allow the designers to more precisely control the level of difficulty in each level; 3. The overall organization of levels into four "skill themes" which are derived from pillars of the game's design--back cover.
