, that why decided to do something simpler as I thought 

Very nice
Also you should think about standardizing the form of your city sets, so that you can just replace the buildings and walls for other ones, keeping the same overall form, to create new sets faster. It is what i do and it saves a lot of time indeed.
I would rather have different styles for each culture and not have a standard form.

Ok, thanks Pounder, I know what guys meant now. Yes, I am going to make all of sizes for city and village too but I started form palace because it was most difficult. When everything will be ready, textures, models, lights, etc, then from finished capitol some building will be taken to make a city and village, the same with walled style.
By the way, is it possible to make three walled style or only one?

About the city walls for different city sizes: Please don´t do the same mistake as most city-creators do for ancient and medievial cities. That there is only one slot for city wall for size-one cities is defenitely no reason to forget city-walls around size-two and size-three cities.

I wanted to make three styles without walls and three with but I thinks is impossible. I made three images instead one with walls for all city sizes but seems to not work. Walled village shows three walled styles at once, tiles of course. Looks doggy
If you know how to do it, then tell me please because I wanted to and I didn't know how.

Simply make the images for size-two and size three with walls (and not without walls).![]()
but you can't make city without walls size-two and size three and with walls and add them during the game, I thought you meant this.
