I have owned the Legendary Edition of Skyrim for a long time. I am unable to make any use of this dlc. I've only bought the Whiterun house and always just use it. Now I will say that I have used this dlc once.
Sure it has a few good perks....like a carriage and sticking a coffin in your basemant if you're a vampire, that and a lot of space. Sure there is a trophy for it on your PSN account or X-Box live. But those are not big reasons for me to put time in to that.
So, is Hearthfire just something to throw money at when you've got nothing better to do?
