I honestly would preach patience but I have to admit, I've been playing this game for less total time than many players and even I'm starting to wonder if Hearth and Home is actually going to happen or not.

At this point either they have enough people playing to have paid for the dev's to hire more people and/or finish the project by now.

Updating a few graphics and AI actions is nothing. Maybe a few day's work? What about the months that have gone by? What's really going on? What is the ETA on release? If you don't have an ETA, then you might as well admit you're not really working on it at this point. I've already seen private servers come and go after waiting for updates that never came.

The only way this game can fail is if the dev's don't do anything.
