I have noticed there is a lot of interest on cooperative quests both in this forum and in bgg, and I would like to collect some expectations (and ideas) we have about it.
Personally I would be very glad if ffg will publish shorter cooperative quests providing more replayability (see the variants I have tested in http://boardgamegeek.com/thread/1247272/increase-replayability-additional-randomness-reduc ) but maybe you have also good ideas for a cooperative campaign.
