Got it. That's pretty exciting, and yeah, I agree; FF6 seems like a wonderful canvas for any setting in general. Chrono Trigger is very much locked into Toriyama's style, and the specific eras make them very distinctive and unmistakable. It did make Trigger stuff deceptively easy, of course (that was the logic behind Crimson Echoes—we could very easily just make a Chrono Trigger 2 scenario without needing to change a ton of location art or doing other graphics hacking). It was a pure bonus that Chrono'99 figured out how to make a faux-elements boss battle, and Agent 12 also devised so many ways to arrange the events.
I want to believe that given those limitations of CT's style, there's still one more good story to be told—but finding that story has totally escaped me the last few years. Crimson Echoes suffered from various issues of its own, but a big part was definitely trying to sandwich it between Chrono Cross and also make it completely mired in the Compendium's temporal theory (which is an achievement, but still amounts to a bandaid on a few plot holes the developers of both games overlooked). If I could make something in the future, it'd be much more of a straightforward Chrono Trigger 2. But alas, it'd have to have a perfect story in order to feel like CT all over again, and really have that sense of 16-bit adventure.
Welp, that concludes the big divergence off topic from my end, haha.
