Are you suggesting that all avant garde creativity is worthless or self-defeating? Impressionism? Dada? Cubism? Surrealism? Wagner?
No, I am not. More importantly, I wonder how one could possibly get that from what I wrote.
I am saying that the label (be it "avant garde" or "bohemian" or whatever) doesn't indicate
value, any more than "blue" indicates value. Sturgeon's Law applies - 90% of everything is crap. That means that 90% of all avant garde work is crap, such that the label itself can't be a direct line to quality or value.
Indeed, none of the things you mention - impressionism, Dada, cubism, etc - are even avant garde any more! Wagner died in 1883! We are well over a century past his work - there is no viable claim that it is on the forefront of art at this point. Avant garde is a
temporary status. Eventually that which was
avant garde becomes either
de rigueur or is consigned to the
oubliette of history (because, really, why leave the French descriptors - they are so fancy!).
But Wagner is still Wagner. Monet is still Monet.
Value does not come directly from being a member of a genre. It comes from the detailed merits of an
individual work.
Are the results of the avant garde I mentioned valuable?
Not all of them, no. There were a lot of really crappy Monet wannabees, so to speak.
Those results include Sorcerer, My Life With Master, Dogs in the Vineyard, and Apocalypse World and its many many offshoots. These games aren't widely played, at least if the measure of "widely played" is D&D in its various versions. I get the impression that many D&D players regard it as pretentious or elitist to prefer these games to D&D. Nevertheless, contemporary RPGing would hardly be what it is but for the influence of these games.
From where I sit, you seem to be conflating, "there is value to be found looking in new territory," for, "being new is valuable." They are not equivalent. This becomes clear in the survivor bias in your statement - you mention a cherry-picked list of games that had influence, but you don't survey the games of that school as a whole for all the
failed attempts that didn't take hold, and didn't have influence.
