Glad you're enjoying it! It seems highly unlikely that we'll be getting those final six packs from FFG, and if we ever did it wouldn't be any time soon, so we're planning on asking the community for ideas on how to complete a "nightmare campaign." Not just for our campaign but also for anyone else trying to do their own nightmare journey.
You guys are doing great! I've been watching through your nightmare campaign and thoroughly enjoying! Hope FFG gives you the final 6 decks!
