great news Johan, we've been discussing various things at the mod threads, mainly in "Mod Idea: The Sengoku Clan Customization Project" and the "Genpei War"
we'd appreciate it if one of you guys took a quick look at the suggestions there.
I'll just drop in a quick note of what's been discussed there:
1- increasing speed to x3
2- adding a tech tree to the game mechanics
3- adding a divorce mechanism
4- more frequent province looting/building destruction
5- unique traits for the clan you're playing, that YOU choose upon starting the game
edit:
i would like to add that, i wish if it was possible to choose your own clan colors, or give us the ability to color the existing clans on the map, i often found myself with colors i dislike or even with a color almost identical to another clan, thus making it a bit harder for me to tell if this is my land or theirs.
i think you should add this and make it possible for us to set "default colors" for each clan. just an idea.
