From what I understand, you can play the Saga scenarios as a campaign as well as individually.
Here's my question:
Are the two Hobbit boxes separate from the four LOTR boxes? In other words, can you start the campaign from the Black Riders box?
If you complete the campaign of the two Hobbit boxes, is there any carryover into the LOTR campaign?
Are they two separate campaigns, or is it just one big campaign? Or is each its own campaign (for a total of six)?
And while I'm on the subject, can you mix cards from the Saga boxes in with the Deluxe expansions when building a deck?
