I know you were planning to provide an expansion pack for Book I (pity that failed), but are you planning on doing anything similar for Book II?
I'm not BW (
), and I can't answer your specific question, but I would refer you to this earlier post from BW
Ultimately, Book II will be a bit better at handling updates than Book I was. So, if the game ships and there is some feature (such as Skill Imbuing) that doesn't make it in before we go gold, there is always the possibility of adding it afterward via a patch. I do plan on offering a few "bonus content" patches in the months after the game ships to keep interest up (and thus revenue flow) while we work on Book III.
This doesn't answer your question directly, but it does imply that Book II will be more 'moddable', which means it sounds like expansions may(should?) be possible.
The open issue is whether BW may release a rudimentary "editor" for Book II, even to just a select knowledgeable few around here (and, by this, I mean people who actually know programming
, as I don't think a rudimentary editor could be used by anybody but people with those skills...), so that we can get some 3rd-party expansions for Book II from fans on this board during the wait for Book III. I suspect the answer is no, but I think the idea has been brought up here in the past...
