Ptolus: Monte Cook’s City by the Spire is the top of my list as far as new gaming products go. The $119.99 price is daunting, but ye gods look at what you get!
I figure that by August I will be ready to get a new campaign going and those few of my players left post Katrina have voiced a desire for some dungeon delving so this may well be it.
Besides, Monte always writes brilliant stuff. This is one of the only gaming products I can think of that I would spend that much on without flipping through it first.
