I've been poking around with ideas to make the Culture (_____) buildings more accessible. Alot of them are very hard to get, and you almost never get them in the city you want. Until you get access to Great Farmers, you can't terraform a city to match the requirements, and some require non plant/animal bonuses.
What I've come up with is splitting the Culture (_____) buildings into several different buildings:
So what you need is one city that has the right combo, that city can build the Local ____ Tribe, then can build the Culture (____). Then in any other 2 cities you can build the Mission and Exchange buildings, which lets you build the Culture (____) buildings. Once you have 3 cities that have them, you can build the National Culture (____) building which give you the Culture (____) building in every city in your empire. The
costs are set so that it costs the same to build Tribe+Culture as it did the original Culture (____), and is cheaper than building Mission/Exchange+Culture.
I've created/modified the XML and tested it, it seems to work. There are a couple annoying things though:
If you guys have any suggestions or tweaks let me know, and if you want me to post the files as is I can do that too.

I've created/modified the XML and tested it, it seems to work. There are a couple annoying things though:
- I don't know how to set the number of buildings required to be fixed and not changed by map size. I'd like there to be a path for people to get cultures to 'spread' even if you only have 1 city that can build it naturally, but on Giant map size <iNumBuildingNeeded>1</iNumBuildingNeeded> gets changed to 2.
- All the buildings use the same icon. Without some easy way to batch edit all 52 culture icons to add a little star or face or something I can't see spending the time to do it.
- If you don't play with the C2C hide unbuildable buildings option there are now 52 new buildings and 156 new national wonders clogging up the screen. They only appear when you have the discovered the appropriate techs, but by the middle ages you can see most of them.
- I didn't edit the TXT_KEY's beyond the basic description. So the Strategy/Pedia entries are just pointed at the original Culture(____) buildings.
