Ok, guys, I just think that this is really unreasonable.
First, in order to talk with secondary characters, devs have to set the postgame after the ending.
Which means:
1) Devs have to change the entire landscape in order to reflect the winner of the war.
So...add a lot of pires and scenes of persecution to mages etc... if Radovid wins.
Add a lot of Nilfgaardians, Nilfgaard flags (expecially in Novigrad), change all the soldiers to Nilfgaardians soldiers, and add scenes of slavery.
Other changes if Dijkstra rules.
2) The side quests would be blocked. Because most of them are setted during the war, and play them after the ending would make no sense.
3) Add a lot of different dialogues to reflect the final state of the world.
It's simply impossible.
Ok so i think you didnt understand what we want, for now we just want the main characters back in the post main-story game. Read some my or some elses posts to understand that we dont want thinhs you just said.
1) Radovid wins? no problem Novigrad is allready full of witch hunters and pires.
Nilfgaardians wins? take of the pires and replace the witch hunters with Nilfgaardians soldiers.
Dijkstra wins? same thing take of pires and replace witch hunters with his "soldiers". The other things you say like flags and other stuff why? this things just happend so Nilfgaardins soldiers are preparing to move away in all cases.
2) You can do this quests before the ending and left behind contracts and other quests that dont require a war to be done. Things that i and others has done, i left behind a lot of secondary quests that are not related to the ongoing war and contracts to be able to do some of them with Ciri after the end. You cant understand my disapointment and sadness when i found you that there was no one left.
3) We dont want dialogs that reflect the final state of the world, just dialogs about their relation I'll make an example:
You ended up with Yenn/Triss? you can go and visit them at home like Kaer Morhen, the shop or some other fast travel location like Vizima, talk to them about the relation and about the past(the last ones are in the game) and then be albe to romance them ( i was thinking of this like a meditation type, every time you romance them you will skip 8 hours) and you can do this like ones every 2-3 days.
In adition to this with Yennefer you can talk about Ciri and with Triss about what happend after they split out in TW2 just few options like: How is Ciri doing or What have you done after we split out ( this are just some examples).
Ciri: if she become a witcher you can meet her in Kaer Morhen, at Dandelions Chamaleon or some other place. Be able to go and do some contracts with her and then talk about her, how it is do finaly be free to do whatever you want with your life, to be a witcher, Maybe her feelings about Geralt-Yenn-Triss and something about the past.
All this is not impossible it can be done in many ways:
>Just put them back in the post main-story with same dialogs thay had in the pre-end, in some place with a hunt and a romance option. (Free or 5 euro DLC)
> Put them back with some new dialogs and other interactions like drinking with other friends and so on. (5-15 euro DLC)
> A new post end-game expansion with new quests and dialogs for main characters, change the world according to our decisions. ( dont know maybe 15-20 euro)
