To begin with, sorry for a rather late reply.
So the key is in doing it as cheap as possible
Obviously. But since there are always a few ways to get a cheaper result, why not thinking of making the European Cities series a 'Lite' type product?
No hi res ground textures plus some buildings you have no photos of could have some kind of custom yet generic textures?
For creating a realistic cityscape enhancing reality in the FS that would be more than enough, wouldn't it?
All in all once the city visually grows in the simmer's eyes, that should be a happy moment for everyone flying from/to this city.
It's very much the issue around the night textures for the US Cities, sure they can be done, but the development costs are so high the product would never make a profit.
I see. What about creating a, let's say, temporary solution? For now you could place generic illuminated windows on the buildings textures to create the impression of night lighting in the building.
Same could maybe go for illuminated spots simulating laplights and cars on the roads.
doing a European city in the same level of detail always tends to be much harder on frames alone for the fact of European cities not being as symmetrical as US cities
A good point. Thanks for the explanation. I am sure though you can find a way around it.
Especially that European cities also tend to be smaller and definitely lower than the US ones.
Just thinking aloud and daydreaming...
