“There is a lot to unlock! There are for example, characters, new ring environments, challenges, victory animations,etc. …there are lots of challenges outside the ring. Some tutorials, training sessions, etc. We packed the disc to the brim and there were a few things we had to leave out because there wasn’t any space left. We are the first internal Nintendo dev team to come across this problem with the Wii’s dvd, so you are def. getting a lot.” – Producer Kensuke Tanabe

I’m an strong beliver it there is any space left on a disk, then the devleoper hasn’t finished their job.
