Ok
But if you think there is may be way theoretically, I will try to investigate.
My motivation is following: Shogun 2 is very good game, but when it comes to battle, it gets completely boring as time passes, since the castles are pretty similar, and with only 7 types and 5 modifications (5th is out, since the PC never finished any as I occupied whole Japan faster) and I want to widen variety. As I can see, your maps are pretty good.
When I will make any conclusion, be it negative or positive, I'Il message you. Btw wanted to know if it is normal to discuss all this stuff here, or better use private messages.

@str1k6r I too don't know how to add more types. I think its not totally impossible if I can use tweak(modding tool) well enough. but sadly I barely know.

I am already too verbose, but I suppose it relates with the campaign map itself (think there are markers of castle positions containing types of castle maps for exactly this location)
This suggestion is based on what I have seen by using Pack File Manager on campaign map mods. They override types, so I suppose these types of castles and other locations are specified in some places on strategic map

Ok sorry finally I found a guide how to replace campaign map (additionally to say, it's your guide, so thanks)))
Here it is: https://steamcommunity.com/sharedfiles/filedetails/?id=2072197524
But I would like to know whether I can increase amount of castle types, for example, add custom "mountain 4"?(following naming provided in your guide)

ok thx for info
btw i wanted to ask if it's possible to increase the total amount of castle maps ingame (as far I know, there are 5 or 6 castle types with 5 levels for each), so the question is if there is possibility to get ingame 10 types of castles (not regarding to levels, since they are bound logically to regions development)?
I'm asking, because although I cont myself as not bad google user, but whether there's no info, or I search for wrong word combinations, but I haven't found any info regarding overall castle types and ways to manipulate them so far.
Thanks in advance :)

@str1k6r all 1-5 will be replaced by single castle.

Are all levels 1-5 replaced by single castle, or there are different castle versions for different levels?

@Misha Krinkov / no. you see required item? on right side? if you subscribe all of them, you can play my maps in campaign. this mod only replace coastal castle level 1 ~ 5 maps

this one will random on campaign ?

What he said is that there is a door on the right side of the map would open itself automatically.
