I love HHD, it really helped me experiment with designing and get an eye for layouts and stuff. I also like being able to interact with all the villagers and having little house parties. Since it really just has the one main focus, I can see how people might not like it, or get bored with it. I think mostly though, people got angry because it's not a mainline AC game and assumed it meant they weren't working on a new mainline game.
