Mario & Sonic (Platformer)

Mario & Sonic (Platformer) (tentative name) is a theoretical game that combines concepts from the Super Mario & Sonic the Hedgehog series.

Premise

After being faced with rumors of Mario/Rabbids RPG, Kay, Apallo, and I began discussing the potential of a Mario/Sonic platformer. It's long been said that Nintendo/Sonic Team/whomever have said that they don't have any ideas on how a crossover could work. The end idea we ended coming up with is something that takes elements from the two franchises and crafts unique worlds and elements from them.

Gameplay

The gameplay mixes up elements of 2D and 3D installments of both franchises. The basic set up in terms of how the game is structured is similar to a 3D Mario; large open courses, but more Sonic like aspects begin to flourish in terms of secrets in courses, particularly ones exclusive to certain characters. 

Aspects

• Mario, Luigi, and Peach are much faster than they usually are.
• All characters's health runs on the 2D Mario principle, but Ring Coins (an obvious combination of the two) remain important to buying things/entering special stages as well as being able to keep the player alive if they have just one.  
• After completing an Act, the player is rated from S to E
• At the end 

Characters

Playable

Emulating the structure established in the Genesis games and 3D World, all of the characters play extremely similar, but with aspects that make them diverse without making them feel too distant. The six playable characters are:

• Mario: The most balanced of the entire playable cast.
• Luigi: Can jump the highest, run faster than Mario, gain
• Princess Peach: Float, able to pick up and toss items pulled from Veggie Buds out of the ground
• Sonic the Hedgehog: Fastest on ground, can spindash and homing attack enemies as  well as sommersaults and slide/spin kicks on the ground
• Miles "Tails" Prower: Flight and can swim faster/better than most other characters and can mess with electroic devices
• Knuckles the Echidna: Almost as fast as Sonic, can punch though dark colored hard rocks and armored enemies, glide ability, great swiming ability

Switching characters is either done automatically when you begin a level or can be done through thematically designed blocks similar to Super Mario 64 DS. Yoshi can also be ridden by the cast with all of them using their innate abilities to change how Yoshi works. The Sonic counter to this is the ability to have partners ala Sonic 2/3/Adventure.

Levels

The game takes place in a HUB world and from there, similar to Mario 64/Sonic Adventure, courses/zones can be accessed. Courses are as they are in 3D Mario games: open playgrounds with a different task given in each episode (or in this game, "Act"). Zones are strictly linear levels that play on the tropes of the 2D/3D games of both series.
