Agree that the symptoms are all there. Not saying it's all over and we won't see anything else from this game, but it's hard to imagine another two years of development and we're looking at only two more days in the life. At some point, surely, L&P will have to evaluate the situation and make a decision about how to proceed.
I can't help but think of GRRM and A Song of Ice and Fire. Let's first remember that the original pitch was for an epic trilogy. The whole thing was really tight in book one, book two was less tight and had new characters and storylines. By Storm of Swords everything was getting more and more detail intensive, storylines and locations grew, new characters came into play, and well, book four became two books, book five became part 2 of book four and another several hundred pages from that were pushed into book six which is now what, 11 years in the coming?
Like AWAM, I really think ASOIAF is fantastic, engrossing and I am anxiously awaiting the next release. And like ASOIAF, I'm becoming ever less optimistic that AWAM will ever be finished.
