ok, what specifically? Is it just that it is shown as a village more than a town, is it the place names, is it the shrine of luck, is it the ruined manor? The images of the buildings and artwork certainly can't help because the buildings can't all be of repeating colors and shapes. For that matter the buildings probably all have the same description- dirty and poorly constructed, and not the plethora of colors, seeing as it is a small semi-medieval village.
so how does the map convey an idea of what the place is actually like that can't be done with a list of notable places and descriptions(I'm assuming there will be descriptions for each place anyway)?
It's a small place, with most of the major places of interest found on its central hub town square. Its ruined wall speaks of defensive measures once required here that are no longer maintained, the ruined manor suggests a place once well-funded by a wealthy land-owner, maybe now facing hard times in their absence, it seems clear that the village's only major means of support are farming and mining, and the variety of colours in the buildings (which I'll choose not to ignore simply because they don't meet my preconceptions) suggest either several phases of construction, or a sense of economic status, with the buildings of wealthier residents being constructed of superior materials. Or the colours could be simply paint or multiple castings of
Prestidigitation, and they were chosen by the villagers to give the place a more appealing look.
The presence of representatives of a trading coster suggests that this village has, or had, something worth exporting, and the lack of any religious buildings beyond a Shrine of Luck means that either this village hasn't felt the need for access to organised religion, or hasn't been able to attract any.
Looking toward the outskirts to the north-east and north-west, the sight of ruined buildings suggests that the village is having trouble growing beyond its current size - or that it was once larger, and has lost ground. Seemingly, there are some dangers nearby that would prey upon outlying farmsteads.
So, yeah, nothing that some descriptive text couldn't also convey, but I got most of that from my first half-minute looking at the map, and if I want to remind myself, I can look at it again. Descriptive text, unless the DM is a great orator, tends to wash over the group in a few minutes' info-dump, missed by half the players who assumed the others were paying attention, and forgotten by half the rest within a session or two.
