Now this is interesting:

Final Fantasy XV‘s notorious Chapter 13 will see some changes this month. Along with balancing adjustments, the team at Square Enix has been at work on a number of other enhancements based on user feedback.

Speaking with Game Informer, producer Haruyoshi Sawatari gave a run down on what we can expect when the new patch launches on March 28.

“So before, obviously, it was just Noctis by himself, kind of alone without the powers of his weapon summoning abilities,” said Sawatari. “But what we’ve done for Chapter 13, is we’ve added a separate route for Gladio and Ignis after they get split off from Noctis, so you actually get to play as Gladio, and see what happened from their side of things until they reunited with Noctis.

“You’ll see some additional cutscenes [that] just show you what took place while Noctis was kind of on his own. You’ll get some actual gameplay with the party of Gladio and Ignis together. You’ll see what happened to Emperor Aldercapt and [Ravus], and where they ended up being during the whole time.

“These are just the supplementary scenes that were added into Chapter 13, and that’s just for Chapter 13. But aside from that, we’re overhauling the ring magic, so the three spells that you could use with the Ring of the Lucii – those are completely powerful now, like super powerful now.”

Sawatari also commented on the upcoming Episode Gladiolus DLC saying it should take players around two hours to complete the whole thing. Those who do complete it can dive into additional modes that offer more replay value and other challenges.

Sweet! That was always one pet peeve of mine throughout the game. I like Noct, I really do. But why can't I have some fun playing as the others? (Except Prompto, I really don't like Prompto.)

I agree! at least the new DLC is letting use play as others, though this option should be available throughout the entire game!

Hopefully they do this for the battle in Altissia as well and we can see what happened to Ignis and how he got blind.

That will probably be part of the episode Ignis dlc

Most likely.

I didnt mind the chapter. You could still easily abuse the ai and kill everything with the ring. But good changes.

That is nice but 4 months late. So this is no longer of any use to me. Had they had this then I might have had less disregard of the game. Not much less but less.

FFXV is an ongoing project, they will be adding more to it for the next 12 months. Once they release everything i'll play it again. Im looking for to the off road driving the most. 

There have already been quite a few major updates. But i also advised my brother to wait aswell. I think after this update it will definitely be worth playing.
