I am someone whose Kickstarter support was driven in a significant way by the prospect of using the toolset. I dove in as soon as it was ready and was eager to put my dreams into reality. It became clear, however, that Larian simply don't have the time right now with other issues taking priority. It simply looks too risky to sink my time into it just to have major issues go unresolved or get broken in future patches. I felt that pain in Dragon Age and I'm not interested in reliving it again.
That said, while I am rather disappointed, I hold no ill feelings toward Larian. I have full confidence that Swen is prioritizing things that are in the best long term interest for the health of Larian, and that is more important to me in the end of the day. The optimistic side of me is hopeful that with the new teams Larian are setting up, we will get a double benefit. Namely, Larian will have to clean up the toolset to make it work better for off site teams with better integration of multiple adventures, and we'll get a steady flow of games from Larian themselves. Here's hoping...
