This is a huge soccer stadium i created in my single player world and imported into its own world.
Ill be releasing parts of the world every once in a while.
Eventually, ill just release the whole world with everything in it.

This is a "save" so to make this work:
go to Start -> Run
type in %appdata%
open you .minecraft folder
drag the "Soccer Stadium" FOLDER, not .zip file, into the "Saves" folder.
Then run minecraft and it will be a world to choose!
have fun and I'd love to see how you guys use this for your own projects!
