Super Mario Maker 2

Super Mario Maker 2 is a 2D Platform and Level creation game developed (specifically by Nintendo EPD) and published by Nintendo for the Nintendo Switch. It is the third and most recent installment to the Super Mario Maker series.

The game was first announced in a Nintendo Direct on February 13, 2019 then released on June 28th, 2019. It introduces many new Course Parts, Game Modes and the new Game Style.

Gameplay
The gameplay is very similar to its predecessor. However, there are a lot of notable difference in the UI made to make it more afitted to the Nintendo Switch hardware. Alongside the similar gameplay, it sports a menu (accessible through pausing) dividing familiar and new modes to that game. Those modes in particular being the Course Maker, Course World, Story Mode and Course Bot.

Course Maker is a game mode in Super Mario Maker 2 that lets you build courses using a multitude of iconic course parts and some brand new to Super Mario Maker 2 and the franchise as a whole. Course Maker divides its course parts into 4 different categories; Terrain, Items, Enemies and Gizmos.

It also sports 5 game styles that can change the rules of the course slightly (some giving enemies, mario, or other course parts unique behaviors in that game style).

There are some Course Parts that are not immeadiately available at the start of the game, and must be gotten from Story Mode. However, most are available from the start of the game.

Development
Development for Super Mario Maker 2 started before the Nintendo Switch was released, most likely starting after Super Mario Maker for Nintendo 3DS was completed. In the beginning, the team behind Super Mario Maker 2 was looking for ways to expand what was possible with the original game and what was what they had wanted to accomplish with this game.

It was also mentioned that the team also wanted to find more ways for players intered in the playing portion of the game to enjoy it, adding new game modes like Story Mode.

This theme to build on the first game can be seen with the project's internal name; "Slope", which refers to the Terrain Course Part that made its debut in this game.
