For all those who finished DAI (base-game), you can check the spoilers for the DLC details.Spoiler
Not sure who has played the previous DLC or if it has been talked about but here is my 2 cents.
DLC #1 Jaws of Hakkon was boring and didn't really add anything important. Story was poor and uninteresting. New location was visually nice. It cost $15 in USA fun dollars.
DLC #2 The Descent was incredibly dumb and overhyped. The story was AWFUL. The ending was especially bad and it essentially causes a big wake-up for the world to comprehend but NOTHING comes from it in the end. It cost $15 USA funbux.
Doesn't set a great example for DLC #3.
