I don't think that is sad/weird/strange at all. I think it would be sad if the average price for RPGs was $120. Being that Ptolus is being published as a premium product the price does not seem to out of line. As I have said in other threads:
The main book will be 600-700 pages of full color, great art, 50 pages of maps, many handouts , and high end production values.
You get a 96 page adveture.
32 page players guide (actually preorder people get 5 copies of this)
A CD with a ton of content.
Access to a special Ptolus website.
all in all you are getting nearly 900 pages of content in print. I would think of buying such a thing as taking a gamble, but since Monte is publishing it I don't feel it is a gamble. I have never been let down by any of his other products and doubt I will be with Ptolus.
