Super Mario Spikers
Super Mario Spikers is the name of a canceled volleyball-wrestling hybrid game that was to be developed by Next Level Games, the same studio that created Super Mario Strikers for the Nintendo GameCube and Mario Strikers Charged for the Wii.
The game was conceived after the release of Mario Strikers Charged and would have been made for the Wii. Initially going under the working title "Mario Volleyball", concepts for new Mario sports projects were being worked on by Next Level in 2006, while Mario Strikers Charged was still in development, and after the team decided upon this concept, development began in 2007. Super Mario Spikers initially started development as simply a volleyball-based game, but as the game was being developed, the team decided to implement mechanics based upon wrestling; Next Level Games tried to combine their knowledge from their previous Mario soccer games with their experience with wrestling gained from the canceled WWE Titans: Parts Unknown.
When Next Level pitched the concept to Nintendo, they rejected it due to the game's violence clashing with Nintendo's code of honor. The violence was too realistic compared to other games with Mario characters fighting, like Super Smash Bros., and production of the game stopped in 2007. Next Level Games proceeded to develop another Nintendo game, Punch-Out!!.
