I [censored]ed and whined when I heard about Hearthfire. My problem wasn't so much with the DLC itself, but rather that I was concerned that we weren't getting new areas to explore filled with new things.
However, though I still want that very badly, I am pleasantly surprised by how much I am enjoying the added "Sims" type element to this game. I actually hope Bethesda expands upon it further.
This DLC is great for RPG as I'm just opening up to the genre. I now spend more time acquirng bldg. material for Lakeview Manor and establishing my steading while trying to create a story behind my character. One thing I would recommend, and others have also stated implementing a "realistic" mode- a need to eat, sleep, and stay hydrated through the adventures.
