Mario & Sonic Generations

Mario & Sonic Generations is a platformer video game made by Nintendo and SEGA. Hence it's name, it is a crossover between the Super Mario and Sonic The Hedgehog and the first crossover outside of the Olympic game crossovers. It is also meant to be a sequel to Sonic Generations. It is exclusive to Wii U.

Plot
The Time Eater, the main enemy of Sonic Generations, has been reborn and wants revenge on Sonic, his friends, and their world. However, this new Time Eater has also discoverd Mario's world and plans to attack the world. The Time Eater attacks both worlds and sucks all of the heroes friends back into different periods of Mario and Sonic's history. Mario and Sonic try to stop the Time Eater, but get knocked out and the screen goes white. They both awaken from their unconsciousness and both of them meet in a white world and wonder what's going on. They soon set off and realize that they are traveling through time and space once again and that they must save their friends and restore time and space by reliving their past before it is too late.

Gameplay
All the worlds in the game are seperated into 6 levels. The first 3 are played by Mario, then the next 3 are played by Sonic.

The Mario levels were worked on by Nintendo. They play very similar to Super Mario 3D Land. The goal is to reach the flagpole at the end of the level while collecting clocks to increase the time limit, collecting coins, hitting blocks, defeating enemies and getting power ups. Mario can preform a single or double jump, Wall Jump, Sideways Somersault, Long Jump, and preform a Super Mario Bros 2. style Backflip. Other moves from the 2D games like crouching and sliding while running, which requires the use of a run button returns too. Finally, Mario has a new roll move that can be used to break blocks from the side and fit through small gaps. The perspective will switch between 2D and 3D, but the controls and moves stay the same. Mario's health system is the same as the side-scrolling titles and Super mario 3D Land, one hit shrinks Mario to a smaller size and removes his cap, while power-ups give him an extra health point.

Sonic levels were worked on by SEGA. They play the same as the Modern Sonic levels in Sonic Generations. The stages consist of running extremely fast through while the perspective switches between 2D and 3D such as in his more recent games like Sonic Colors (Wii) and Sonic Generations (Console). The player can perform Combo Tricks, which can be used to fill up the boost gauge, by using special objects. There is a new visual element to all returning levels. There's a bit more platforming involved as well. The camera is also immovable unlike in Sonic Unleasehed (Console) and invisible walls can hinder the exploration aspect.

The HUB is the same as Sonic Generations. The HUB world starts out as the white space, but opens up more as the heroes pass through more levels. The Hub worlds are only playable in 2D. One character is rescued in each stage. Characters rescued will stand outside the entrance to the stage, and they can be talked to. Also, there is an area above the entrance to the main stages where the player can access extra missions and rival battles that are unlocked after beating all the worlds in an area. Bosses are accessed through special areas known as "Boss Gates", found at the end of each area.

Worlds
All the worlds in the game are either based on levels from games in the main series, or some levels from the different spin-offs, and they have all been completely reimagined as well. The levels are also divided into 8 catergories. The Mario catergories are 2D, 3D, Mario Kart, and Mario Party. The Sonic catergories are Classic, Dreamcast, Modern, and Sonic Riders. The levels from the spin-offs have now been completley reimagend as full Platforming stages instead of their original race track or party board format.
