I think they should sell the source code so that people can make their own spinoff versions and host them for themselves...
but make it so that they can still communicate via a universal client
500 bucks per sale sounds right to me... they can keep their own little game here but I think it would be cool if people could make their own for a one time fee and they would upgrade/optimize graal making it even better than before

from players for players like a few of you said
I dont like the idea of the people stealing source code though... there should be some dependency er somethin that wont allow people to just dload the source compile it and run it....
