I tried it out and had an excellent time! The new buildings really add to the game.
Like you said, most of the new buildings are under powered but under powered is much better than most cultures having nothing in the base game.
Great Work!
Thanks for the positive feedback! If you have any suggestions on balance please let me know and I'll see what I can do!
Appallingly noobish question, but how exactly does one install this mod?
Where and what specifically am I unzipping?
The file that you download is a zipped file with 2 items inside, a folder and a .mod file. Extract (unzip and move) the two items inside the .zip file to the /mod folder inside your Crusader Kings II library, wherever it is installed.
The path should look like this \crusader kings ii\mod
And inside should be the Culture Buildings folder and Culture Buildings.mod file that you downloaded.
