Have to admit, in some regards I got closure with Legends 3's cancellation (at least in terms of cause), but hearing fans provide the voices, and extremely well too, does bring me to wondering what could have been. I can't help but feel a little regretful for it. Nevertheless, I hope the GMOTM crew keeps up the great work!
You can find more direct footage from Five islands Adventure on the Rockman DASH 3 Revival Project Blog.
