It could be worse. I remember a situation with comics Daireiger V, when G9 announced last chapter and people for several months everyday bombarded his blog and Pixiv, asking if the chapter already done.
That was kind of on them though. If I remember correctly, they specifically said, before even the first chapter was released (paraphrased):
You will NOT have to wait months to finish the comic. Pretty much everything is already done besides the last chapter, which we'll finish soon.
Of course no one should harass the creators, but when a project goes past 6 months their initial time line...
Anyway, if you guys are impatient for the update, I can reveal I've been working on a huge update to the Isis prequel. I won't promise a release date (heh), but I think it will come out before the Valdana update, if you guys want to play that while waiting.
The changes will include comprehensive improvements to the entire script and fixes, including a fix to the long standing bug in both Falls games of multiple videos stacking and playing simultaneously (so look forward to 120 high refresh videos).
If that release goes well I'll maybe do it for Valdana too.
