I'm pretty sure that we Will reach the 900k for the John book SG, and also (as a Munchkin collector) that the content in the box is above the total of the content bought indepently, and as You stated before, SJG don't want to lose money with this campaign. With that being said, I believe that the Best 1M SG can be a small new Game Changer expansion set, such as bosses, dungeons, side quests, Munchkinomicon, Fairy Dust, etc. A small 15-30 card pack exclusive to backers. Something that add some depth to the Game, knowing that most of us backers, had played munchkin for some years now. I think it's the most "budget friendly" we can get, and a very much appreciated one.
