Its not magic. Its actually rather obvious if you understand tourism. Each unique you place increases your effective maximum of tourists. You still need parks and commercial for them to generate revenue but the unique will pay for itself through the tourists.
Tourists have been a very obscure mechanic for a long time and Parklife only made it a bit better but was able to confirm for me the beneficial effects of tourism. So its understandable a lot of people don't figure it out.
Promethian,
I own the base game and SnowFall DLC expansion only.
Maybe the economic/finance dynamics work different depending on which DLC's you own, but for what I have, the numbers displayed by the game do not "add up," and thus some "magic" must be present.
My city currently has 125K population. I have lots of parks and quite abit of commercial spread-out throughout my city (a mixture of both low-density and high). My public transportation would be described as good to very-good.
If I click on Info Views/Tourism I see the following info: "Weekly tourist visits = 955" and "City attractiveness = 57%."
I have so far placed down 18 Unique Buildings from the total of 30 that are available.
From the first image attached below, you will see that my city only makes "Weekly total income from tourism = 3,569." This number breaks down to these two sub-categories: "Commercial zones = 127" and "Public Transportation = 3,442." (By the way $127 from commercial zones is laughable).
From the second image below, you will see that my "Weekly Unique Building Expenses = 17,936."
The difference between income and expenses here is a whopping loss amount of -14,367.
I have plenty, plenty of money in my bank account. My overall weekly income for everything (the amount we are used to seeing at the bottom of the page when we play), has for some time now, shown a loss. But my bank account is either stable or goes up very little and slowly (so I am not concerned). So I am not complaining about money, but all I'm trying to point-out is that money is "magically" being made through other means, because my tourism income is nowhere near my Unique Building expenses.
PS: Can you compare these two numbers in your city. I'm curious if your numbers make better sense than mine. You don't need to include images, unless you want. But can you at least post the two numbers. Thank you.
PSS: I thought you were one of the forum members that was involved in this debate/issue in the thread I described earlier from about 1 to 1-1/2 years ago. And I thought you did agree, at that time, that money was "magically" appearing for the finances of the game. But maybe I am getting you mixed-up with somebody else.
