Books like Ultimate Campaign and Ultimate Intrigue introduced a bunch of rules subsystems for mass combat, kingdom building, nemeses, and so on. These are fairly easy to find because they're all in the SRD in the "other rules" section. But it's come to my attention that some Golarion-specific products have similar material which did *not* make it into the SRD. For example, Lands of Conflict has a militia subsystem which is essentially a more generic version of the Hell's Rebels rebellion system (which I loved), and which I can see being very useful for any campaign with a lot of intrigue.
What other Golarion-specific products are like this? I'd love to have a big index of them for ideas to mine for homebrew campaigns.
