I'm thinking it would be as simple as adding in new parts in the ship creator, if you wanted to add on to an existing hull style. I mean, thats not a huge mod, but it would count.
Is it possible to add in addition hull styles with all your own custom parts?
Can you Add in extra races? Like a custom race with a pre included attributes/portait?
Basically what im asking is what all can you do in adding new content?
