10 Franchises That Should Go Open World

8. Mario

Mario has never been stuck for fresh ideas, but I still think the series could be great in a non-linear format. The 3D series has always revolved around hub worlds, and these have held some of the series' best secrets. The secret sections of Peach's castle, the collectibles in Delfino plaza; they are often the most memorable locales of their respective games. Whether it was 2D or 3D Mario, the secrets that could be hidden in an open world would make for a hell of a platformer.
