It's a good all-around supplement to a third of the outer planes, and gives plenty good ideas to how to use them in games - with the usual Planescape caveats, of course. Plenty enough imagination. The sample adventures are all pretty rubbish, though.
3 for 1: sweet deal (Planes of Law, Planes of Conflict, Planes of Chaos) for one spot on goodreads.
Need more Planescape literature (and good fiction) please! Incredible mind-expanding ideas and fantastic presentation (despite my inherent dislike of gratuitous piercings and tattoos and ear disks, yuck! what have u done to yourself?).
And hey, who wouldn't want to visit tranquil Elysium, or pleasant Arborea, if not furry filled The Beastlands aka "The Happy Hunting Lands?"
I also noticed the word "barmy" on the 1954 publication Lord of the Flies (pp. 165 "If we don't get home soon we'll be barmy."
PS. The ideas and presentation alone blow my beloved DragonLance campaign setting/world away which is saying something because DragonLance was created with such love and thought and care. Margaret Weiss and Tracy Hickman to write for Planescape please!!!
