I've been slowly watching through all of the modding tutorial videos that have been posted, and I haven't found a tutorial on how to set up a mod for the main campaign, so I wanted to ask if the instructions found in
this thread are still the way to go about doing that. I think that topic was made right around the time the game was coming out, and I've gotten the impression the toolset is, or at least was, still in development.
Most of what I've seen in terms of modding the main campaign has been mods changing game balance or items, or things like that, so I also wanted to ask if it's possible to add quests to the main campaign as my interests lie more along those lines. That other topic says it isn't possible to mod existing entities, which I assume means I wouldn't be able to add dialogue to existing NPCs, but if I'm mistaken about that it would be good to know. Also, if I missed any threads about this that were more recent, feel free to point me in the direction of any posted information that I missed.
