We picked this up to try out. I got both hard copies and PDFs. I didn't know what to expect. This isn't a module, this is far more than an adventure or two, this is an entire multi-campaign setting where you can pick and choose what you want to use and surprises await around every corner. It's even put together in such a way that your party could step away from the area for a bit, and come back again and again for all new exciting adventures without ever repeating anything.
With RPGs it's the journey and not the destination that makes it worth while, and with Castle of the Mad Archmage as your main campaign or even asa suppliment, that journey is one hell of a ride.
