Seriously I don't get it people say it's lame... Clearly it ain't Dragonborn but it's 5 bucks that did exactly what it said it would... Buildable houses are awesome, adopting children too! It really adds to your RP so I just don't get the hate at all
Some people just want to adventure, quest, build their character, and collect gear. I'm not interested cause I'm one of these people. I think the people who liked Hearthfire simply don't talk about it as much as the haters do.
Only one of my characters is a 'family man'. I'm building up the house slowly as I progress through dwngrd and drgbrn, and will eventually adopt when the world is 'safe'. My other main characters are all races with no like adoption options and no fitting wives found yet. None have finished one entire house let alone all three.
Obviously the annoying bugs associated with the various houses/spouces/children/etc put me off a bit, but I think Hearthfire is well worth the price of admission.
