kolt54321, I don't know how would we decide is a particular idea/scene/dialog is good or bad, should be implemented or not, but if you need some vizualization/realization of your work then we can provide so. I still will work on other areas for now, but Prizvel definitely can do story-related stuff. At least something like heavily commented script code to distingush modified code/scenes from original, partial implementatin (to let you see how your additions looks in-game), etc.
Also, I recommend you to read full Chrono Cross original script, even if you already did it or completed game many times. Just because you really need a starting point of view even for almost blank characters.
I don't yet know how we should organize stuff for teamwork yet, I will prepare single-disk for further use right now.
