Planescape left its mark on D&D in terms of the Blood War and yugoloths for starters. Sure, both things originated pre-Planescape, but the setting's spin on the whole thing was not contained to Planescape. We could start another thread to Planescape, so we can retread old shark-filled waters, but I would prefer not heavily engaging into this topic that I know has gotten quite heated in the past.Where is it's "truth" imposed? It uses the GW as the assumed cosmology... but that's no different from any other setting that assumes their cosmology is correct. But I'm unsure since the campaign setting makes it pretty clear belief can change nearly anything (including the structure of the multiverse) how it preserves, upholds and defends the status quo of the pre-existing power structures. What it does is give you a baseline and says go at it... It's almost like you want them to enact the changes for you and that IMO would be missing the point... the point is for your Players to enact said change through their PC's... not for them to script said changes out for you.
Even for children, the ideas of deconstruction do not have to be needlessly deep. (Though I will grant you that deconstructionist writers tend to needlessly obfuscate.) It can simply be pointing to alternate readings or gaps of the text. It's when a system of authority insists that the painting represents a rabbit, and then someone comes along and says instead that it looks like a duck or that it could even be both. It challenges the primary reading of texts. It challenges core assumptions and systems of authority.Well I think you've got Planescape as a setting wrong as I stated above but even if you don't... not sure as a child picking up Planescpae I necessarily wanted it to be that deep... if I want postmodernism on that level I'll play Unknown Armies, while with Planescape I get the tropes and themes with a much higher level of accessibility due to the familiarity they keep by using the GW as the assumed cosmology.,.
But with Planescape it seems that belief does not shape reality because the Great Wheel remains the Great Wheel and no one believes anything other than the Great Wheel so the shape of reality remains a stagnant bore. I can see Planescape as a setting for fun, planar sight-seeing adventures and urban factions. On the other hand, many of its ideological conceits fall flat on its face for me. It tries to be postmodern, but it propagates sophistic-nihilism at its core. The more that I think about it, the less that I want to. Every time I try approaching the setting with fresh eyes - because I do find its Weird Fantasy charming - its ideological conceits push me away again. I do hope that it gets an Eberron-style book from WotC, but I am personally always repeatedly disappointed by the setting. It's just not a setting for me.
