I found out how to change the title of any ministerial position, including the faction leader's.
Requires:
Pack File Manager.
db file:
Open 'main.pack' with the Pack File Manager. Go to db -> ministerial_positions_by_gov_types_tables -> ministerial_positions_by_gov_types. Here you will find a table containing almost all ministerial positions, specified with country, position, government type, gender and the link to the localised string is localisation.loc.
Nation:
The country it belongs to - obvious.
Position:
The position with the name used with the engine.
Possibilities: army, finance, head_of_government, justice, navy, faction leader, governor_europe, governor_india, governor_america.
Besides, there are a lot of ministerial positions that do not apply yet to the game: governor_asia, governor_africa, monarch, spouse_of_monarch, royal_heir, spouse_of_royal_heir, royal_child_1, royal_child_2, royal_child_3, royal_child_4, royal_child_5.
Government:
To which government type it should be applied.
Possibilities: gov_absolute_monarchy, gov_constitutional_monarchy, gov_republic
Gender:
The gender to which the specified title should apply to.
Posibilities: f, m, b.
'F' is the female title, 'm' the male one and 'b' applies to both genders.
Title:
Directs to the localised string of the title in localisation.loc.
localisation.loc:
First make sure you edit the localisation.loc the game loads as last. So, if you don't use a separate pack file, you have to edit the localisation.loc file in patch.pack. If you do use a separate pack file, you have to set the pack action to 'Movie'. Then you will also have to manually specify your mod in user.empire_script.txt, by inserting the following line:
user.empire_script.txt can be found or made in:
Code:
<Windows drive>\Users\<Username>\AppData\Roaming\The Creative Assembly\Empire\scripts (Vista users)
<Windows drive>\Documents and Settings\<Username>\Application Data\The Creative Assembly\Empire\scripts (XP users)
In the .loc file, clone as many rows you need. Then edit the left column so it contains:
Code:
ministerial_positions_strings_on_screen_<title>
Where <title> is the string you entered under Title in the db file. Edit the right column to your wish, this is what is actually displayed by the game.
Lazy?
For people not wanting to do this all themselves, I have provided a small mod (with English localisation file) correcting the faction leader's titles for a number of nations. http://www.twcenter.net/forums/showthread.php?p=5236475.
