I confess that I am a Bathroom Reader, so I may have missed this if it's covered in the book already: Is there anything in the book for scaling the campaign for characters who've already been through the campaign in the core box, or is it meant to be a continuation. Conversely, if it IS meant to be a sequel, is there info on scaling it down for starting characters?
A corollary to the second question would be how one should bring the new characters from the box up to speed if someone wants to switch out one of the ones who's been through the main campaign.
Also, three adventures? I know it's not a huge box, but hope Return to Hoth's is longer.
