Alot of the DLC is just a good way to make up some money and exp . Some of them do add more content such as a demon or town and some more story . Then there are the armor DLC. All really good in their own right but I would say it's better to only get the free DLC plus the what extend the game paly. I don't mind spend the money to support the company once in a while tho cause it gives them a chance of making more really good games .
