This is what I'm looking for... But how is it done? If RTR or anyone else has done it, where can I find their relevant text files? (don't tell me to download the mods to get at the files, the MBs will kill me...)
Then I can use them as samples to modify my vanilla version :)

Regarding ZoR:
ZoR -in the cases I've seen it applied- seems static, based on preconceived notions on who is (or may be) native in any given region (I am referring to the employment of hidden resources as unit training conditions), so it does not allow for population dynamics to truly evolve during a 200 year campaign.

Besides, let's assume that 1) Egypt can't train Pharoah's Guard in Sparta due to ZoR restrictions -reasonable enough- and that 2) the Egyptian AI player is majorly expanding and currently contemplating sending an army there to capture the province.

I don't know how the AI bases such decisions, but I bet it will be really frustrated when it discovers it has gotten a (militarily) useless province, which it can NEVER hope to develop... It should have conquered something more usefull. Worse yet, it won't be frustrated; it won't even know what's happening...

So basically, I imagine that ZoR is a usefull concept only to human players, the AI hasn't been programmed to use it (ZoR is largely a modded feature, not like mercenary pools). I imagine that the only reason poor AI usage of ZoR goes unnoticed is because the AI is always on the defensive/ not expanding enough to be hampered by the restrictions/ etc... Please tell me if you know otherwise.
We can bypass AI decision making handicaps if we remove the " requires factions {...} " from the export_descr_buildings.txt, as in the RomeTotal ZOR I just had a look at (thanks for the links ER), but that effect is definately not what I am looking for.

So back to plan A: Hopefully, the AI is smart enough to destroy structures it doesn't need...(?) Do you know where I could find hard info about what Spartiate suggested (i.e. his quote segment in bold, see above)?

Thanks again guys
