I agree... I'm expecting solid quantity for my CE, not just for the cloth map, but also for the hardcover books. I will be very unhappy with a simple 20-page booklet. Given that you can add the books as add-ons to your pledge for $50 each (and that I'm expecting separate add-ons to be a bit more expensive than the packaged deals), I'm expecting at least $40 worth of retail value... which means they should be closer to 200 pages than to 20 (compare them for example to the limited hardcover versions of the Prima Game Guides, which are usually also full of lore and artwork - for example the 512 page Pillars of Eternity CE Strategy Guide, with a retail price of $40).

As for pricing... if you want to set up a successful KS campaign that will not only give you enough money to fund the product, but also keep your clientele happy, then you should either offer the people the product below retail price, or offer quality exclusives that will not be available in the retail editions. Personally I don't think $125 for the CE is all that much, if you consider all the stuff they put in it, but yes, that is based on the fact that I'm expecting large and high quality versions of those two books. Those two books are the main reason why I went for this CE, instead of another version.
