It depends on how you look at it. It would be a bad thing to sell graal to Nintendo because the chance of it being more for money than for fun is high. However, on the flipside of that, there would be better quality stuff, hehe, especially, cause Mr. Miyamoto might work with it
I bet if the right things were said, it would be possible to sell graal to Nintendo and keep it at its current state, but with better servers and stuff. But that is my opinion.
Personally, I am for leaving Graal as it is right now. Graal is centered around its players and Nintendo might ruin that.
