I'm always good until I start having to make the separate high-tech cities and the "Gridburg" city. My suburb is over 30,000 sims, and my power city has 10,000 jobs of dirty and manufacturing. I then add some high wealth and try to make the High Tech cities, they grow a decent size, but then gridburg only goes to 5000-10000 sims. I dont get it. Also, there is a big demand for R$ but once i've put school and water in my city, only medium to high wealth people move in.
can anyone help?
