Playing SimCity 4 with a tiny experimental city today, I noticed something interesting.
Say I have a residential area that looks like this:
interior 6 blocks high, 10 blocks wide each housing lot is two blocks deep ╔════╦╦════╗ ║↑↑↑↑║║↑↑↑↑║ ║↑↑↑↑║║↑↑↑↑║ ║←←→→║║←←→→║ ║←←→→╚╝←←→→║ ║↓↓↓↓↓↓↓↓↓↓║ ║↓↓↓↓↓↓↓↓↓↓║ ╚══════════╝
(It's connected to a small amount of medium-density industrial and low-density commercial, enough for the residential to fill up.)
Now if this area completely fills up with low-wealth housing, for a total of 26 houses, I'll make a certain amount of tax revenue per month. Now let's say I surround this block with the various items necessary for higher-wealth housing, e.g.:
- elementary school
- high school
- clinic or hospital
- police station
The houses start to turn into medium-wealth or even high-wealth houses. But as they do so, they get larger. A single high-wealth house can grow to take up the entire right side of the block:
╔════╦╦════╗ ║↑↑↑↑║║HHHH║ ║↑↑↑↑║║HHHH║ ║←←→→║║HHHH║ ║←←→→╚╝HHHH║ ║↓↓↓↓↓↓HHHH║ ║↓↓↓↓↓↓HHHH║ ╚══════════╝
No matter how much of this block turns into medium- or high-wealth housing, I get essentially the same amount of revenue every month. It's as if, even though a single medium- or high-wealth house produces more revenue, I lose out because there are comparatively so few of them.
Previously I've always striven to make as much of my city high-wealth as possible. Now that I see that this has no effect on residential tax revenue, what good does it do?
