Not that I wouldn't want it, but this ROM hack literally got a cease and desist letter from Square Enix back in the day. I think that's proof enough that the rights holders aren't going to agree to having it hosted by an official store. I'm not voting for it.
Though it's a little sad- I was looking forward to seeing the story continue- it was also clearly not the story that the original team would have come up with. So, even from a creative standpoint, not a legal one, it's completely understandable that they didn't want their own story told in a way they didn't approve of. This is what copyright was originally intended for, to allow original authors freedom to tell their own story the way they want, and to encourage individuals to come up with their own stories. It's still, IMO, not fair copyright lasts so long now, but that's a separate issue.
This happened before the big indie game breakout. I think fans were feeling a bit trapped, not having a Chrono sequel that told a plainly continuing story, and having game development generally gatekept by large companies. With how relatively straightforward indie games are to make and sell nowadays, I don't think a project like this would start nowadays. I'm not sure what to feel about that. But I am thankful that we have such a varied developer landscape now. There are many, many games that were clearly inspired by Chrono Trigger (and its 16-bit RPG contemporaries) which are unfettered by having to live up to its legacy or continue its story. While not many have the same polish that Squaresoft presented us with, I think we are in a better place now than the alternate world where indie creators had not been encouraged to flourish. And, sad to say, this project's cancellation was part of that encouragement.
Square Enix, we would welcome another Chrono game. Really, we would. I know getting something resembling the original team would be hard, but I don't think another entry could come at a culturally better time than now.
