It was also Balkanized America built on demographics that just can't match up population-wise, even with VITAS.
The worldcrafting has some holes that get more glaring the more you look at them. What they want to be there doesn't fit with the world they made.
It also suffered from some power creep in the game that got progressively crazier, and some "everyone is special" garbage by year of the comet where everybody's a metahuman with some special metahumanness and every super-local myth had its own metahuman variant. "No, I'm not a green-haired dwarf, I'm a central-southeastern black forest kobold and my mother was a Orkney island kelpie." It was like a game made of tumblrisms.
It also made the "you'll never see one of these" rare things turn into something that was all old hat and everything and everyone was one, no matter what it was.
I remember the early novels being pretty decent.
The recent games were okay. First two felt like Shadowrun, complete with power creep that got absurd, and plenty of too-special characters. Last one felt like Shadowrun tumblr, where the "I heard a rumor about a rumor about an urban legend about this once" rareness of characters are half your party and everything you encounter.
The computer games suffered from mechanics where the way to progress is to get good at full auto rifle fire and just burst and full auto every damned thing, because other than that, whatever traditional character role you wanted is already taken by one of your teammates, and probably with custom tweaks that make them uniquely better, and you'll find your character superfluous.
I think I have all 5 editions of the game, and basically have used 1, 2, and 3. 4 and 5 are just "lets see what they did now" followed by "why did they make the text small, change the font, and put it over a picture or textured background and still expect me to read it? Did they hire the guy who did White Wolf's Book of Nod or some shit? Fuck it, we're playing Rifts cuz I can use the main rulebook and still read it."
