Yes, I am building it alone on a creative map for the purpose of making blueprints. Since it is in creative mode, it only took a day to build. The brainstorming part is the most time-consuming. I'm taking a break at the moment for future builds.
I accidentally deleted all my previous blueprints for the cyber city. Now, I'm starting over and I've written a collection of sci-fi stories that are hidden within the city, inspired by Black Mirror. It's about 200 pages long. Visitors can solve clues to uncover these stories.
