If you're too lazy to modify your own files-or want no inflation in multiplayer with friends-I made a fork (my own version) of this mod that works in the current, Re-Awakening version and integrates Community Fixes

For anyone else, I figured it out. According to Kaneeden earlier in the comments, you can find the base game's own "SimulationDescriptors[Empire].xml" file in the path \Endless Space 2\Public\Simulation.
The only value I changed was "DustInflationFactor" to a value of 0.0002 which seems pretty balanced to me.

You can jury rig fix it yourself by copying the new SimulationDescriptors[Empire].xml over the old SimulationDescriptors[Empire].xml and changing the dust inflation values with notepad++. This will let you load the saves that are flagged with this mod atleast

doesnt seem to work after awakening patch

Any chance of updating this for awakening patch? It crashes upon starting a game.

@Type Definition
DustInflation BaseValue="0.001" MinValue="0.00025"
DustInflationFactor BaseValue="0.00002"
worked well for me so far with an healthy inflation around 2% in late game on a huge map, it scales with map size, number of enemies etc so on a small map with few enemies 0.0001 could be advised.
setting it to zero breaks the game in some edge cases so don´t put any zeros in there or crazy things will most likely happen XD
e.g. the calculation of revenue from trade lanes and its growth are also connected, and 0 can break many calcs.

I would suggest fulltexting all the xmls for inflation and see what I missed.
But 60% of the time, this mod works everytime. :-D

What values should I put in the XML to disable inflation?

Seems its working not right, on Turn 30 the Inflation hits like a Truck, a Building that costs before 150k, after 5 Turns it costs 1500k.

love it

I like this mod so much i gave it a reward, don't ask me what that means or how it works but hey, le fancy treasure chest seemed fitting.

@Eksangha you can edit the SimulationDescriptors[Empire] file yourself. just search for dust inflation and put some zeros infront of the min value and the dust inflation base value and you should have almost no inflation with achievements

It took me a while to understand why everything was taking more dust over time. A neat idea but, as you said, they REALLY didn't balance it. Doesn't really feel like your empire is getting any more powerful as it stands.

shame, but it is what it is

all mods disable achievements afaik, no matter how purely cosmetic they are

would this disable achievements?

You're the hero we always wanted but never deserved!

tysm its honestly kinda broken to be at war then next thing you know your -400 dust beceause the fust inflations at -600

most likely, it is somewhat sloppy and not overly compatible with other mods fiddling with the thingy

For some reason this isn't working for me. I'm playing riftborn with Arkon mods.
Would this mod have any incompatabilities?

go to the forums, see the years of arguing on this particular topic.
But tl:dr if any faction can sell 10 adamantium for 5k cause inflation. Lumeris are not exactly winning.

also random thought, doesn't inflation actually help the lumeris?
sure, prices going up seems bad for you. it is, but it goes up in relation to the total dust generated in the galaxy. The richest people set the pace, and the smaller factions are hurt more

could you possibly make a mod that has less inflation rather than none
like a half or quarter of vanilla values
