Oof the length of time I spent thinking about this very idea... thanks for bringing it up! c:
This is not entirely out of the question. The thing is, when people have tried before, they used things that currently exist that they may not have had permission for or were not royalty free as well as the title itself, which belongs to KovuLKD and other respective owners. The idea is not just to make a FeralHeart 2, because we can't, but a new game like FeralHeart but literally everything would need to be created from the ground up, including the ground, no preexisting things used at all. Also as Jango mentioned above, I'm not sure anyone here could manage it. I can do single-player stuff and small local multiplayer but anything involving online networking is beyond me.
This would be a monumental thing to try.
