captured_required_region_prestige_multiplier. Did you get this to work? Why do you use the term capturing a region" when that's not in your pack. This mod is not good for WRE, ERE, Sass. It starts them at level 6, which makes the former 2 doomed much earlier in the game.

It is possible to make a mod like that, sure. I don't think it's something I'll be working on though. You'd have to find every source of imperium points and set each one to zero. This would be the technologies table, campaign_variables, and building_levels at least. I'm not sure if there are any sources other than technologies, regions/hordes controlled, and buildings.

Are you able to do a mod which removes Imperium Gain completely?

Nevermind what I just said. I took a look at the building_levels table, and there are actually quite a few buildings that give prestige points. However, except for some buildings in Charlemagne, most of those values are very small (1-4 points per building, depending on level). I could adjust those, but if I do, it'll be part of my larger mod, Europa Perdita, so this one stays compatible with other building mods.

I'll check that, but I don't think any buildings give imperium for the Alans. I think the only ones that might are some level 5 buildings (maybe the Celtic ones?).

Do you know if certain buildings in the vanilla campaign give imperium? I noticed while playing the alans that building a storyteller's tent seems to be giving me imperium. Oddly when I destroy the horde with that building though, I only lose an amount equivalent to the loss from losing the horde.

Yeah but improved technology doesn't automatically make you into an imposing empire, which is what Imperium is supposed to represent.

But, it's historically inaccurate. Let's say roman apeducts which were a great technology, it exist many valuable written resources on how prestige was given to them in the eyes of the rest of the world.

I could, but that's not what I want this mod to do.

You could easily put Researching a technology - 2 prestige

Maybe it's a little easier for hordes, as they'll have a little slower imperium gain - though they will be affected by the imperium gain from vassals (tributaries), so it may balance out, depending on how you play. If it's too easy for hordes, I can increase their imperium gain from new hordes too.

Oh this is great! I've been looking for something like this for ages! Wouldn't it make things lot easier for Horde factions though? (not that they had an easy time before)

I think it's not historically accurate, nor logic; ut a great work. Thank you.
