I would like add the reason to why I didn't talk about the alternative ending. It feels shoved in to me and it definitely does not feel like canon. Kind of "too good to be true" scenario. I think most fans would agree with me?
15:45 if Episode Ignis was in the main game then im assuming some stuff would've been tweaked a little to keep the pacing of the game intact or maybe it can be similar to Chapter 13 verse 2 where you can get like a Chapter 10.5 or Chapter 10 Verse 2 as something like a bonus after you defeated Leviathon and finished Chapter 10.. Sorry if my english and explaination was bad. Great Video btw! I adore this game so much!
