I am more than satisfied with the houses, great textures, architect etc, but they all only look European/vikingish, and tribal we need houses for more cultures such as sultanate style houses, or Chinese looking houses. Walls and castle variations should also be added, such as style 1, style 2, style 3 and etc. seeing plain stone walls with plain stone castle in a desert would feel very fake, maybe in the future you can add sandstone and sandstone walls and castles.
It's just alpha but just an early heads up
