It could be their first game. They could be unexperienced, they could be sick, or tired, or busy. BUT! - Is this really so hard - to come here and tell everyone "everything is okay, we are working and game will be done soon" or "we are tired from gamedev and we are not planning to finish"??? This is normal practice and such doing separates thoughtful people from indifferent ones. Because of this I don't want to wait their game or buy existing side story. For me, will be better to spent money on something not abandoned.
