I only had 2 cities when that problem occurred. I decided to put it on hold and start claiming more land. I tried out new road and avenue patterns and I made a 3x3 square with each square being a avenue square, so 9 of those and then turned those into a 3.3 square. And put a academy in the middle. 6 are residential and 2 are commercial. The problem is it says the Density is to low. I can draw a road between each one of those squares and divide those into 4 sections. But then the buildings don't have the maximum area to build for the avenue towers. But the density won't increase. Any ideas?

well, this is my first successful city. The taxes are low, im in red, but the recycle and processors and the space station is making me more profit. Problem is, that I have certain areas with buildings with ground pollution. No room to build. people are leaving, because they say my taxes are to high, even though im in red. Im not sure how to do it. The arcology project is started, wont receive and recources, and my electronics hq wont level up because the highest processors I can sell per day is around 500k, and I need 1.5mill. I havnt researched the mega towers yet because I want to enable fusion reactor and research clean energy ahead of time, before I start any more cities.

I have a university in my city, and a population of about 70k. On the info menu it says 800 people can attend, to start a research project it says it needs 1000 in a day. I placed all 3 dorms near the university and the 800 didn't go up, but it now says that around 850 people attend my university in a day. How do I do this? I need to start a research project.
