Blue Rose is fascinating because it's like people don't understand the setup value of having a relatively utopian state surrounded by dystopian or at least non-utopian ones. It's a really strong setup for a campaign honestly.
And these people have watched Star Trek, read The Culture novels, yet they still don't get it! If the main society had weird-ass values like, say, Cormyr does (which is sometimes presented as sort of utopian, but is gross because it's a weirdly bureaucratic scraping-and-bowing-mandatory monarchy where Midwest-esque "yeoman farmers" are somehow the backbone of society), I could see it. But Blue Rose and similar societies aren't doing anything weird. And like, if there was a game where the PCs were like Special Circumstances from The Culture, people would be all over it, but the moment you're Special Circumstances in a fantasy setting, oh no we can't have that!
(Radiant Citadel I think I would question whether that's actually a utopian situation, because it's got that classic 1980s D&D "we slapped this setting together from disparate and incoherent elements and ideas we thought we cool, without really seeing if they fit" deal going, accidentally I suspect. I mean, on one level that means a lot of the haters are wrong to hate because that's absolute classic D&D there baby! There are times, for example, where it lapses into a sort of "authoritarianism is cool so long as the authorities are on what I perceive as my side" mode too, which ill-befits some of what it's doing, and other times where it's sort of trying to do IDIC but like, imho without real conviction, which makes it ring hollow.)
