I still think it would be better to let Abelius update the old version while the new version team does a Better demo, so they can do it calmly while people have fun with Abelius, so they can do an amazing demo, they can even deal, Abelius can make the old version, but everything he invents can be used in the future in the new version
(sorry for the english)
I once raised a similar idea on the pages of this forum, but then I still did not know the whole situation of conflict between developers.
To work on an abandoned version, Kuja is required as artist and Abelius for almost everything else. So even if, for some reason, the current team decides to pretend that they are primarily interested not only in money, but also in the opinion of all fans - even as they will stop fighting and hand over the abandoned project to Abelius - he will not be able to continue it as it is, since Kuja will be busy by other project.
On the other hand ... Why not? ... What's the point in keeping the project dead as an advertisement if one of the main devs of it will decides to revive it?... It seems to me that this gesture can be an excellent test of which of the developers is a really worthy person, and who only plays this role.
So, if Abelius will wish to get his third child back (common with Kuja, and I apologize in advance for the fact that this phrase may not be understood unambiguously
) - why shouldn't Kuja just give it to him? ... Without all this copyright fuss and ego ... Just convey it, and give the opportunity to somehow revive this project? ...
So the decision is up to the developers. And this decision will be a good test for all of them.
