These courses will only be the tip of the iceberg, with Super Mario Maker allowing players to create and share levels.
We have to assume that the initial 100 levels will be brand new, although we may see some remakes of classic levels sprinkled in.
If not, I am sure the Super Mario Maker community will work on recreating some of the classic side-scrolling Mario games. Personally, I would love to see Super Mario Bros. 3 and Super Mario World recreated by the community.
Instead of classic levels, perhaps we will recieve sheer Mario madness! Some of the levels played at the Nintendo World Championships were absolutely crazy.
For those excited to create their own Mario levels, or to explore the levels of other creators, Super Mario Maker comes out on September 11th.
