Hello greifvogell,

Shogun can be modded indeed, the Warlords edition/Mongol Invasion more so than the original Shogun: Totalwar. Unitproperties can be changed by using a texteditor on TroopStats.txt and Projectiles.txt.

It's also possible to create new campaigns, historical battles, historical campaigns and maps.

There are some things that don't seem to be implemented/used or work differently.
