Also, about your last question, if you own RPG Maker MV and setup the modding environment, it's not very hard to edit or add dialogue :)

Have completed 3 or 4 RPG maker MV tutorial and yes, adding and editing dialogue is quite simple. I tried to have a look at your guys' scripts stuff and can only understand like 5-10% of them (I have very limited coding experience, can only do some easy stuff in Matlab), i think i need take some time to learn some JavaScript stuff. For me, your guys are amazing and talented XD
