Looking at the list that describes which buildings boost morale and which lower it, I notice that some buildings are on both lists.
For example, "Factory" is on the [U] list (morale plus) and on the [W] list (morale 2xminus).
This applies to about 10+ buildings, so the list seems sort of unusable to me. Am I missing something?
On the top, you have the Factory
On the bottom, you have Factory x 2
(Essentially, its 1/2.)
This means that the Factory has a negative affect on Morale, but not as much as other facilities (like those that are not on the top of the fraction at all).
The reason it isn't simply just put onto a list at the bottom with half the effectiveness is because fractions aren't quite as simple as that.... It isn't neccessarily half: it would only be half if only factories were there.
This is presumably to make the facility equation really REALLY hard to optimise. :)
