i had a think about where i got the idea to build this map, but there really isn't any answer. it sort of came from nowhere when i wasn't paying attention. now that i've put a little bit of effort into it, i'd like to finish it.
the map started when i made world brush arch for a different map (which has fallen by the wayside now) and joined a few copies of it together. i thought it looked promising, so i put a building face around it. i liked it, so added a few more touches, eventually replacing the world brush arch that started the map off with a more detailed model version.
there's still a long way to go, and i've not really got a firm grip on exactly what direction to take it, but i've enough ideas to keep me going for a while yet.
