Create a large modern city called Central City built on a flat world. The city should be about 750 blocks wide and 750 blocks long. Buildings can be up to 400 blocks tall. The estimated total block count should be between 350,000 and 500,000 blocks. The city should feel clean, modern, and technology-focused. Use bright modern materials such as glass, concrete, quartz, and metal-style blocks. Include a downtown area with tall modern skyscrapers, a business and science district, and a river running through or near the city. Add wide roads and highways throughout the city. Include a large STAR Labs building with a simple interior space, a Central City Police Department building, and a Flash Museum. Avoid fantasy or medieval styles.
