It's really amazing how easy Ara: History Untold is for modding.

The first thing to know is that all the source data files can be found (if you're on Steam for instance) in a directory like:
C:\Program Files (x86)\Steam\steamapps\common\Ara History Untold\assets\SourceMods

So say you don't like one of the balance of say...Recipes. Let's go find that.

Recipes0.zdata is where all the recipes are.

Now I happen to be a bit unhappy that the Feast recipe is defaulting to using money instead of food as its accelerator because this is causing some new players to feel like they don't have enough money.  So I'm going to fix that.

Before:

to:

So I have changed it so that food is teh default option in the first slott and grains in the third and nothing for the second.

Now I'm going to pop this into a new file:

Then save it to the Mods directory:

Then I just have to make sure the game will know about it which involves adding a file called GameCoreData.zdata:

And that's it.

To use it in game you just click on Mods.

and Enable it.

If you did something wrong, the game will tell you and show you the logs where it will explain what you missed or what typo you did.

Now when I start my new game:

It takes a bit longer but as soon as I get grain it will automatically use it.

If I want to share it with others, I just have to go over to http://www.modio.com

And voila.
