By "environmental descriptions" do you guys mean the storybook portions of the PF and PoE? I love those! They're a nice way to change up the pace and present challenges without combat. Plus you get to see some cool hand drawn art. 🙂
Not that, all the other description during normal dialogue. Personally I just found it to be exhausting.
Hmm I have to play the game still, but I can see how it can be a bit much if that would go on in excess. If there are cues its trying to convey, "the character seems pensive or distracted when they reply to you." or the like would be fine. Not sure what a full description like RR Martin got involved would be needed for, other than say, accessibility though I wouldn't know how a visually impaired person would do a game like that.
