Create a large modern coastal city called National City built on a flat world. The city should be about 750 blocks wide and 750 blocks long. Buildings can be up to 380 blocks tall. The estimated total block count should be between 350,000 and 500,000 blocks. The city should feel bright, heroic, and futuristic while remaining realistic. Use modern materials such as glass, quartz, concrete, and clean metal-style blocks. Include a downtown skyline near the coast, a waterfront district with piers, and a government and business district inland. Add wide roads and highways throughout the city and a coastal road running alongside the ocean. Place one large bridge connecting National City to Central City. Include ocean water and beaches on one side of the city. Add a CATCO Worldwide Media buildi
