So what are everyone's hopes for DLC and Updates?
We know Episode Ardyn is coming, but what about the other 2-3? I personally think we aren't going to get specific character episodes for every single one of the remaining DLC.
I'll start with Ardyn. I personally think there are 3 options for the setting of his DLC. Option 1 could be that it takes place 2000 years ago with him and his brother, while he is a healer, going about Solheim helping people as well as the tragedy that befalls him. You learn more about the Astrals and who Ardyn was. You would fight Shiva before resurrecting Ifrit. Option 2 could be that it takes place in Gralea/Nifleheim with the ability to travel in your sweet ride while you learn more about the secondary villains as you rise to power in Nifleheim to get closer to the Line of Lucis (he didn't become Chancellor without effort). Option 3 could be both. The main crux of the game takes place during the moderate past (Option 2) while plenty of story based flashbacks from thousands of years prior occur to learn what drives Ardyn (Option 1) and even maybe having some playable scenes. I could see this being implemented into the main game after chapter 13. This would solve some Niflheim/Gralea expansion issues while fleshing out starscourge/astrals/secondary villains more. It also will likely make Ardyn's fate that much more sad by the end.
We know something has to happen about Luna. Tabata has been pretty coy about what they are actually planning with her. She's not a fighter/combatant so making a DLC where she does those things would make little sense. What I can specifically see, or personally hope to see is a DLC side-story where Noct and her actually do something important around the region of Accordo. The boat would be the main source of transportation, but you play as Noctis while Luna acts as your caster. Provide that sense of love and companionship that was missing from the main game. This can be chapter 8.5 and integrated in the main game, like Ardyn's. I really don't know how else you incorporate her more into the story, unless they just plan on adding more cutscenes with her. This would solve the expanded Altissia/Accordo problem as well as more character development for Luna.
I personally think character episodes should and might stop here (though Luna's wouldn't be a fully dedicated character episode) and the rest should focus on fixing and expanding the main portions of the game. While the above 2 would add to the main game logically, the 2nd half still leaves much to be desired. I personally think "DLC" 3 would not be a paid DLC at all, but rather a larger update to the back half of the game. Tabata says that he wished he could "smooth out" the transition of the first half to the second half. The easiest way to do this is to give players more to do during the second half. I don't expect Nifleheim to ever be fully explorable (even in Episode Ardyn), but rather have smaller open area's to explore. For starters, adding in the open area that was intended for Niflheim (likely the area in Cartanica) for exploration and new monsters would be great. Add a stop between Cartanica and Tenebrae; make the world feel alive, there was another cut train station (we only stop at 2 technically) that looked very far into design that I'm sure most people know what I'm talking about. Potentially make that a nice small town with a small open region that you can only travel by foot and not by car. Next, make Tenebrae a small region or large dungeon to explore, whilst giving more about that region. Lastly, make the region around Shiva's body explorable. Add a small snow town or something. Either that or make a dungeon near her strictly. This way, the transition from open world to linear is smoothed out if it goes like this::: Chapter 10: Coastal town and station where you board the train (decent sized area to explore by foot)-> Cartanica (Sizable open region with car travel enabled; several areas of interest) -> Chapter 11 plays out the way it does -> Train station town (smaller open region strictly by foot; 1-2 areas of interest) -> Chapter 12: Tenebrae (Large dungeon) -> Shiva/Snow town (smaller dungeon) -> Chapter 13: Linear section that would make much more sense at this point. This would be the biggest update of the bunch but should seriously alleviate most people's concerns about everything up to that point.
Chapter 14 will be our "DLC" 4 and could likely be another free update. Unfortunately, Chapter 13 doesn't leave much opportunity to explore Gralea (Episode Ardyn may help potentially), but I do think chapter 14 will get updated in some form. It has been confirmed by Tabata that we will see Cor/Aranea/Iris/Cindy post-timeskip at some point (correct me if I'm wrong). I think Comrades will strictly stay Kingsglaive related with its updates and potentially give new bits of story here and there, but I do think Chapter 14 will get entirely revamped to allow you to explore the WoR (or at least part of it, perhaps even just a major quest) with Iris. I believe Iris will get the focus here specifically since Cor and Aranea got more focus as allies in 2 DLC episodes. I've been trying to think of a motivation behind why they would explore the WoR, since it is just essentially just a darker Lucis, so there likely has to be some sort of story or gameplay benefit to doing so. Maybe finally getting some story updates for Gladio/Iris (if not done for them in another, earlier update) about how their Father's death affected them. I would say the driving force could be a daemon Glauca, as it could give Noct, Gladio and Iris some sort of emotional closer in that regard, and also solve that story related gap. Tabata has stated in the recent game informer interview that he "wants to go deeper into the background of some characters and personalities". Absolutely fanfic here I know but I just wish I could actually fight Glauca and not watch Nyx do it.
But this only would cover the first portion of Chapter 14. Tabata has repeatedly said he'd love to incorporate Insomnia more into the game. I think expanding Chapter 14 in a way that allows Insomnia to be more explored is very important. A way to do this is to just let the characters travel there by foot with a few loading zones (it would take waaaay too long to actually travel there by foot realistically). I think also improving the ending bossfight would be nice as well. It's either this or they utilize Insomnia in some sort of prologue or flashback.
Anyway this is my dream update along with a rewarding Hard mode and a more refined ending/final boss. I'm sure some of this will happen to an extent as some of it has been hinted at before (More insomnia, Episode Ardyn, more Luna content, post timeskip Iris, etc) and much of it may not or at least in the form that I'm describing. I am also hoping to be surprised by stuff as well. I have been trying to wrap my head around what the "Completely new gameplay experience" he was talking about and how it could tie into anything, but hopefully it will be great. Tabata said in the game informer interview that everything would be tied heavily to the main story, which is why I think these would work. There are other things I definitely would want or do see coming (such as more exposition between Noctis and Regis/Dawn Trailer footage)
As for feasibility, I think it can be done. They were able to create 4 DLC's with entirely new gameplay mechanics, areas, cutscenes and voice acting within a year and under pressure focusing on other types of content (VR, Mobile, Pocket edition, PC Port, etc), so I think another year, with 3-4 more DLC's or patches of this scope along with updates by the Comrades team can be done. Regardless of what happens, I think we are going to have some pretty great updates to A) The structure of the game and B)The story and presentation of it.
Sorry, I type a lot when I get excited.
