I would like to know why players think that something is not well written. Or what is important for you to say it is well written?
Because I rarely saw any explanation to it, so it is hard for me to imagine what other players do have on their mind - what is does represent for them when they say that?
I have my examples of what it could be (not in the order of priority):
1. the right kind of language fitting the speaker's background
2. richness of choices or some sort of feel - like how many options, what is left out etc.
3. connection to the quest - dialogue in an interesting quest
4. connection of the quest to enviroment - does it feel like it does belong to the surrounding, if you would be exploring, would you expect the quest there - so not only what it is about but also how often it is there.
5. connection to the world - escalation of the story - like you don't know anything at the beginning, then you slowly start to be dragged in
and also examples in other games:
I do like writing in Skyrim - that is why I wanted to know reasons of others. I can see, that it is not as detailed like Witcher 3 dialogues - it is more simple, because that is what I guess was the goal of Skyrim, but still I do like it I feel like I would be in that world, it does fit for me. And I did experience games, where they tried hard to have the top quality dialogues and it was boring for me after some time anyway - so what is that for you?
And this is in Skyrim topics because I don't remember the other TES games so well to talk about them. And I wanted to ask about Skyrim specifically
