Another aspect of using a game engine to visualise a town is that you can progressively add seemingly mundane details that flesh out what life really was like.
WayFinding
Game engines use a sort of programming called Wayfinding which is similar to what happens when you ask googlemaps for directions.
You can put a character in one place and then tell it that it has to be in another place by a certain time. It will then navigate its way to that point. Similarly to googlemaps, if you need to move from one point via other points, you can tell it to do that as well.
No imagine what you can do with this capability if you look up a county directory and know when the postman makes his rounds. Automatically, you can have him do his round however many times he works his way around town each day.
More speculatively, you could make every member of the C of E leave their place of residence in time for the Sunday service. Now you can't know whether every member attended that particular service, but as a way of visualising the bustle of a village, it can be a great indicator.
On work days, if it's known where someone lives, and where their place of work is, you can have them leave and walk their way to their work, school children can go to school at the appropriate time, and the local train or coach along the turnpike can pass through.
Another idea is that if you know when a burial, baptism or marriage takes place, it should be possible to have the game engine automatically have anyone within - for example - a kinship of three degrees make their way to the ceremony.
I don't just highlight this because it would be cool to watch - which I think it would be.
Using Wayfinding, you could discover how far people were from their place of work or worship - individually or on average. You could also determine, which butcher or grocer was probably the one they used because it was on the way home, or maybe discover that future husband passed future wife's home every day on the way two and from the fields.
Almanacs
If you know when and where you are looking at in a study of a village, there are preprogrammed assets that will calculate the location of the sun, moon and stars.
I haven't come across any of these that are free, but there are some that are not too expensive.
The rising of the sun may dictate when some people go to work, and as I recently heard on a Google Hangout, the phase of the moon may dictate when religious meetings occur (so that people can find their way across the moors by its light).
