I hope that some of the talented creators out there revisit their creations and put them in to the world setting. Probably not a small task to make it gel together, but i would love to play through some of the more polished efforts in a thematic layout.
It would be lovely to have AYAMMM levels like this (a world for each week), and would massively inspire me to play them, but i'm guessing only one creators levels per world.
My only concern is that it looks like you might be limited to only creating one "game"/set of worlds? The way it showed it in the menu as "Super Ronnie World" or whatever looked like a single game per creator.
Obviously the course upload limitation of 100 means you could only make two full 40 course games anyway, but I hope you can have multiple smaller collections, rather than just one contiguous 8 world collection.
Only been able to watch the update video once (low volume with distractions), but I don't recall any mentions of secret exits on the world map. Would Nintendo really forget about the most important thing?
