It takes me a long time to produce maps, as a matter of fact, I've never technically released one. I spend weeks working on detailed concepts, and make several test-maps to see if it plays well, than I spend time creating customs textures or models, and finally I work on the detail, of all my maps, which I've been working on for months now, most are in the detail phase.
What about you guys? How long does it take to do your process?
