The mod stopped working a long time ago, but I found a solution:
1. You need to go to the root folder of the game: ...\SteamLibrary\steamapps\common\Endless Space 2\Public;
2. Find the file Registry.xml and open it with notepad;
3. Open the search bar (ctrl+f) and write "assim" in it;
4. In the line, replace "2 + $(Assimilated Populations Count) * 1" with "1 + $(Assimilated Populations Count) * 0" - then the cost of assimilation will be 1 piece, but you can experiment, maybe something more interesting will turn out (assimilation from 0 population? :D )

Мод перестал очень давно работать, но я нашел решение.
1. Нужно зайти в корневую папку игры: ...\SteamLibrary\steamapps\common\Endless Space 2\Public;
2. Найти файл Registry.xml и открыть его с помощью "блокнота";
3. Открыть строку поиска (ctrl+f) и написать в ней "assim";
4. В строке заменить "2 + $(AssimilatedPopulationsCount) * 1" на "1 + $(AssimilatedPopulationsCount) * 0" - тогда будет стоимость ассимиляции 1 штука, но можно и поэкспериментировать, может получится что-то более интересное (ассимиляция с 0 населения? :D )

ok cheers, Happy New year dude

I remember the normal as 2, 5, 8, etc. but I may be misremembering.

Even if it were only 2, 4, 6, etc. the micromanagement to get exactly the right number of a pop so you can use it up is annoying, and grows more so as planets fill up. Even with my mod I get burnt out playing Gene Stealers after one game, but at 1, 1, 1 it's just too OP.

So, the following is correct for Splicing costs, yes?

This mod : 1, 2, 3, 4, 5, 6...

Vanilla : 2, 4, 6, 8, 10, 12...

I just looked at the mod contents, and it's a one-line XML override so I have a hard time believing anything that didn't also intentionally change that value would conflict with it.

Sadly, the game assets are compressed so I can't trivially search the DLCs for a matching string; it will be a couple hours work, not a couple minutes. I can't promise to get to it in the near future.

I have generally only played with all of the available DLC installed - though I turn off the stupid latest one. But again, I don't think any of the DLC have touched the Gene Hunter values in the config file. Hmm.

Perhaps it's the DLC used. When I played this, I only used the Vaulters DLC or vanilla.

Hmm, I wonder if they changed something in the declarations; it worked fine the last time I played a gene hunter, but that was a while ago.

The actual change is really tiny. I'll try to remember to check on this when I have some free time. Sadly, work is pushing hard on me right now so ti may be a while.

The mod doesn't work, even when it's the only one activated.

@Daisuke what other mods are you running?

Doesn't work for me which kinda sucks

Mod works perfectly and I love it. The Horatio shall rule the galaxy!

This mod works great. Don't waste any time on the other one unless someone else can confirm they got it to work, i never could.
