Question #2: The Intrigue and Dark Ages campaigns have been fixed. I can recommend them. The Base Set campaign is pretty dull, and the Seaside and Prosperity campaigns still require silly numbers of zaps. Hinterlands and Cornucopia don't even have campaigns yet.
I think Adventure mode has been on the back burner for several months now. I do wish they'd fix up the starting hands for Seaside and Prosperity. That seems like a trivial change.
I gave them new lists for the base set but they haven't used them. They have the lists for Hinterlands and Cornucopia (and Alchemy).
I gave them starting positions that got harder, like they wanted, without getting unbeatable. My plan was, act one you have two zaps and don't need them, act two you have two zaps and need them, act three a rule modifies the game to let you deal with the computer's starting advantage. I'm not sure that will ever happen now, or at least it may not happen as once planned. It might happen though. When they came around to the idea of not trying to milk zaps, they seem to have lost the need to have act 2 start out where act 1 ends etc.
Anyway I don't know what will happen there. Dark Ages and Intrigue aren't in their final forms though, they have some quick fix but there is still fixing to do.
