One question:

is there a difference between improvements that make citizens happy and those that make citizens content? If so, how in tarnation do I make them? I can only see an option for making happy citizen improvements in the editor. (plus: the Temple civpedia entry says it makes unhappy folk content, but the editor says it makes 1 person happy! Ack!)

use Civilopedia noob :p
(in short, you can't, though they carry over, and yeah the editor is misleading)

Happy Faces
^
^
^City improvements, wonders, entertainers, and luxuries produce either [content] or [happy faces] in the
city where they exist.
^
^{These Produce this}
^* City improvements content faces
^* Wonders content faces
^* Military police content faces
^* Luxuries happy faces
^* Entertainers happy faces
^* Entertainment happy faces
^
^Each happy face affects the $LINK<mood=GCON_Moods> of one citizen.
^* Each [content face] makes one unhappy citizen content.
^* Each [happy face] makes one content citizen happy.
^
^If there aren't enough faces of the appropriate sort in a city, extra faces will have a limited "carry over" effect. For example, if a city has the capability to generate 5 happy faces, yet there are only 2 content faces in the city, then those 2 content faces will become happy and the remaining 3 happy faces will carry over to unhappy citizens at reduced efficiency.
^
^Certain political events, such as winning or losing battles and wars, can also influence the overall happiness in your civilization's cities.

You mean the vanilla Civilopedia actually works? Holy crap! :lol:
