So I have an idea for a sort of Star Wars/Force type of mod, with interactions, socials, skills, alignments like the Sorcerer mod, maybe genetics if there's a way to do it. But I have no clue where to start with something like this. Can anyone give me any tips or perhaps we can discuss what I want so someone can guide me in the right direction? Thanks

If you've never modded before you need to start small, otherwise you're going to be overwhelmed and it may lead to you abandoning the project. It really just depends on what you want to add. If it's only interactions. etc. like you just listed (and not custom animations), you might be able to get away with doing 90% of it in Mod Constructor, which will make things easier if you are a beginner (though not entirely recommended as MC makes tuning files messy to read). Skills will need to be done outside MC, as well as injecting traits for inheritance (I assume that's what you mean by genetics, a trait that passes down?).

So just a basic guideline would be something like:

1. Start outlining your mod ideas of course. It helps to know what you want to create, how many of this or that, etc., then find stuff in-game that does something similar and write it down for reference if needed.
2. If you need to override anything from EA, do that first. It will help you understand how to work with files, and begin to understand them.
3. Start with basic interactions, like socials, in MC to get a feel for how they and the program works, which will also teach you buffs and loots.
4. Then start making some traits. Since you learned how to make an interaction already, which also taught you buffs and loots, this should be easy.
5. And anything else possible in MC can be done after this and you should have a grasp of how to do most of everything.

Then after you've done the bulk of the mod in MC you can start on the skills and whatever else isn't possible in MC. At least, this is just what I can recommend based on your outline.

I came here with probably a somewhat similar idea and the same question. Have you looked into this further? Please let me know if you're interested in help
