I agree -- a rulebook or even and extract from it would be valuable. But I've heard very good feedback on this one from two people that sat down with the development copy.
I've ordered two in the hopes that selling the second copy at or near MSRP when it becomes harder to find will defray part of the pre-order cost of the first. Given MMP's short print runs the pre-order price is likely a pretty safe floor for resale. I'm blessed with income right now so I can wager a bit, and with luck this strategy will mean my copy costs me $40 plus shipping.
Would it kill you to put the complete game in the first box?
It's worth noting I haven't actually played yet, but built it in a way that seemed to make the most sense to me based on my reading of the rules and scenario book. The designer has used it though, and he seemed satisfied.
