subsets of the city like a university or park should have to be profitable, but the game only tracks city profit and not entity profit.
Thus, I find unlimited money kind of liberating and I like not worrying if building and bulldozing is done multiple times as I work on some construct. money would just be a constraint until the first couple of super industry cash cows get off the ground. But now I feel I know the game and mechanics. In the past, I used to play for money and suggested beginners do as it acts like guard rails to teach about the game mechanics (at least until the mid game).
