This is a really nice set of three hard-cover books. Well printed,
colourful, and contained in a solid cardboard display box.
Excellent professionally drawn illustrations on almost every page
add real value to the content rather than coming across as hollow
filler. Definitely gift quality, if you're curious.
I would have liked to see an errata supplement pamphlet covering
recent rules changes, but perhaps 4e is too new. The discussion of
skills challenges is really weak, as well. This is a new feature of
4e, so more care should have been taken to really clarify it.
A 30-day trial of the subscription-based web site they push several
times would have been a nice touch as well, given the price of the
books. The absence of that can hardly be held against the books
themselves, though.
(Edit: The ad for the web site at the back of each book does in
fact mention a 10-day free trial on the site. I believe it's a
subscribe-and-we-won't-bill-you-if-you-cancel arrangement, though.)
