I really was expecting this to be an isekai spin-off using FFI world and lore, but holy shit this is actually canon prequel. Despite all cheesy and memeworthy storytelling, this game answers so many questions left from original game. Not all of them but at least the core reason why Chaos existed is explained here. I'm really bias about this but FFI is my top 3 best FF all time and playing this makes me feel satisfied, so much that my tears fall when seeing the ending.
