When we were creating Cypher, we wanted to create a full and explorable city, but the catch was that we wanted it to be empty. And feel empty too. We wanted the towering empty structures to really convey loneliness when you're walking around the city. You also get a feeling for what the city is like, its bright, neon, and colorful, but at the same time, it lacks life. Which we found to be a great contrast. We found that the huge, industrial/cyberpunk neon theme fit well in this situation.
