My 2, beyond just the tech difficulties, but the vision of what we can do.
What is the pinnacle of modding? A: Elder Scrolls.
D:OS probably thinks/dreams of how can we compete in that space.
However they have a totally different vision on what can be modified. It seems to me they see or want people to make new campaigns from scratch. While Elder Scrolls have a couple of these over 10 years, 99.8% of the mods are adding to the original content and that is what D:OS is trying to keep us from.
Imo it is a mistake. It takes a lot of time for a campaign. While many would just love to tweak and add to the current game. To me it's one of those things where you are look deep for answers and it is right in front of your face. I'm not so sure why they are so protective of that, it will make the modding community many many times smaller than what it could be.
I could be wrong.
