BIG JV fan here.
Martin’s care with naming things and people, and his tendency to describe the physical context of events in an evocative way that puts you mentally right there at the scene (right down to details about food), always struck me as the most Vancian aspects of his oeuvre.
They’re subtle things, but they give both authors’ writing a kind of 3-dimensional solidity that’s very satisfying to read; you’re always (as it were) hovering over the shoulder of the protagonist, right there where they are, and the way peoples’ names fit their characters sets a background vibe that substitutes for the subtle emotional cues you get from people in face-to-face contact.
Martin’s occasional use of florid speech with consistent formalisms is also reminiscent.
Reflecting this back to videogames, it reminds me of the perennial discussion battle between first person and third person fans - some think one more immersive than the other, and I’ve always thought that (apart from in narrow spaces like dungeons, where first person mimics fear-based tunnel vision) third person is more immersive, because although you don’t have that kind of third person overview in real life visually, it substitutes for the saccading, scanning and aural cues that we unconsciously do to build up a model of the world around us.
In the same way, although in real life the names of things and the names of people never coincide with their actual characters in the way they do in Vance’s or Martin’s books, the coincidence of naming with what things are substitutes for the kinds of intuitions and emotional cues one has about people and things in real life. It provides an extra dimension that leaps off the page.
