Super Mario Maker

Mario Maker is an upcoming game creator application for the Wii U which allows players to make their own 2D Super Mario levels. It allows players to insert blocks, enemies, items, and more from the original Super Mario Bros.; it also contains some new modified power-ups, such as a Luigi Mushroom that changes Mario into Super Mario by stretching Small Mario's sprite. The game also allows switching between the graphical styles of various 2D Mario games. The game was announced at E3 2014 and is set to be released in September 2015 (originally early 2015), as part of the 30th Anniversary of Super Mario Bros..

Development
Shigeru Miyamoto had shown interest in developing a user-generated Mario game since at least 2009, citing the Mario Vs. Donkey Kong series and Flipnote Studio as examples of Nintendo products already featuring such content to demonstrate how open he is to the idea.

Graphical styles
The game will give players the option to choose the graphical styles from various 2D Mario games. There are four styles announced thus far and it has been stated that others may also be available in the final game. These games include:


 * Super Mario Bros.
 * Super Mario Bros. 3
 * Super Mario World
 * New Super Mario Bros. U

So far, each style will be used for four traditional themes in the Mario series, but it's unknown whether any of the world themes of the later games will be used. Also, while various enemies and blocks that didn't appear in certain styles can be used in said styles, with new assets that make them suitable for the respective games, it's currently unknown whether the game-exclusive items of the later games, such as the Super Leaf and Cape Feather can be used in them.

Differences from base-games
Although the recreation is mainly faithful, there are some minor differences in each styles. For example, in the original Super Mario Bros. game, Elevators could not be jumped through from underneath; this was possibly put in place to remain consistent with the Lifts in the New Super Mario Bros. series.

Sharing system
Mario Maker will have a dedicated way to share course creations with the rest of the Mario Maker user base and Nintendo is implementing a system to share courses online, similar to what was done with Pushmo World and the later games in the Mario vs. Donkey Kong series. Players can even create worlds, which are set up like in Super Mario Bros., with four levels per world.

Customization options
Mushrooms and most enemies can ride on top of other objects and bounce off springboards. Enemies can have wings added to them; in the case of Goombas and Koopas, it makes them look and act like their "Para" variations. Red Koopas can be spawned by shaking a standard Green Koopa until it turns red.

Enemies can be made huge, and players can drag some items and enemies onto Bill Blasters, Lakitus and Pipes, which will make them produce that object.

References to other games

 * Mario Paint: Undodog reappears, and sometimes a Gnat roams through the screen. Also, the game's logo is similar to the title screen of this game. A frog icon on the left in the edit screen is the same as the one used in the music composer mode. The eraser icon is also the same. The rocket that deleted everything on the screen also reappears. A robot icon also looks similar to the robot that appeared when saving something in this game, when selecting a level to play in Mario Maker, the screen used is also based off of the robot.
