Curtis D. Carbonell, in the book "Dread Trident: Tabletop Role-Playing Games and the Modern Fantastic", wrote "Planescape's sophistication marked it as D&D's answer to its own simplistic medieval-European-inspired fantasy settings, [...]. Planescape channeled the Weird before China Miéville brought the 'new weird' genre into focus [...]. With Planescape, we have an attempt by an AD&D game setting to add layers of intellectual complexity to a game often driven by much more simplistic mechanism. The greatest commerce isn't loot, treasure, magic items, etc.; it is belief so strong it can shape reality".
