This was initially planned alongside the apartment system I believe, I don't know the status of that still happening though.Make it so players can make PKW-Courses on the MCC Island Server
Implementing this would make it easier for players to make maps for PKW and consequently, would make great variety in every single game.
I do not think many players even know you can make maps, because it is a feature outside of MCC Island. Furthermore, you could make it so people can look at each others maps and practice them, but that is a bit far fetched.
And it's not like they have a lack of submissions at the moment as they have over 1000 submissions in queue. :)
