CivWiki:Policies and guidelines
CivWiki has various policies and guidelines which guide how to edit CivWiki.
In a nutshell, CivWiki defers to Wikipedia policies. There are some exceptions, since CivWiki is not Wikipedia.
Defer to Wikipedia
Wikipedia has been around for several decades and has encountered almost every combination of circumstances or editing conflict under the sun, and has developed an extensive set of policies that make for a good encyclopedia (of which CivWiki is one). Replicating this collection of policies alone on CivWiki would be an enormous effort. When CivWiki has nothing new to add, we will not state a policy at all, and instead simply defer to the relevant Wikipedia policy.
This includes policies like Wikipedia's Manual of Style, naming conventions, and policy on consensus, to name a few.
In short: in the absence of a CivWiki policy to the contrary, assume that the relevant Wikipedia policy holds.
Not Wikipedia
Although CivWiki defers to Wikipedia, CivWiki is not Wikipedia, and it contains exceptions to Wikipedia policies.
For instance, CivWiki's notability policy is significantly less strict than Wikipedia's.
