For anyone who has ever dreamed of creating their own dream "Mario" course, filled with many elements from the "Mario" franchise, and then getting to play those courses as many times as they want, this game is the game for you! Not only does this game allow you to create practically any Mario stage that you want (as long as it has appropriate content and an appropriate title), it also allows you to play any stage you create in four different video game graphic settings. There's "Super Mario Bros.", "Super Mario Bros. 3", "Super Mario World", and "Super Mario Bros. U", and all four graphic modes are available right from the start. As for designing your own stages, you only get a small selection of tools available right from the start, but you can easily earn more, by playing the "Super Mario Challenge" mode, exclusive to the Nintendo 3DS version of this game. While some of the stages are easy and relatively straight forward, other stages can verge on the HARD side of being INSANELY difficult to defeat, requiring quick reflexes, and outside the box thinking, in order to complete every single challenge, earn every single medal, and unlock every single tool available within the game. If you manage to complete all 18 normal worlds AND the hidden 19th world available to play within Coursebot, and earn all the medals available for all the stages, consider yourself a TRUE Mario master, than extend the fun. Try making your own stages, even stages that are similar to stages NOT found within a Mario game. The course design is up to you! And the best part of these custom made stages, in order to upload them to be playable by ANYONE, they must first be beaten by the creator themselves, in order to PROVE that they are beatable! This game is definitely a solid choice for the video game player on the go! That's why I'm giving this game a solid 9 out of 10. Enough said, true believers!
