Wow, I just noticed in the small jpeg that I have a broken poly... which is why the ocean has invaded a building! Ah, the fun of using CAD programs.

30 hours is about average for a decent map. A full world map would take about 30 to 50, and the secondary detail maps another 50 to 100 hours. I have worlds that I have many hundreds of hours into maps, detail maps, and glossaries. I'm doing this tonight mostly because I am too lazy to work on my current project...
