So,
A friend of mine recently purchased Descent and we spent a day playing the first campaign using the "Road to Legend" App.
This is a game we're going to be spending some serious time with and, given his birthday is rapidly approaching, i figured i'd get him one of the expansions. This begs the question:
Which?
We will almost always be playing just the two of us, cooperatively and using the App. What expansion would add the most value to us?
