Most definitely. Or Tekumél. It's an elaborately detailed setting, with its own conlang included, but in many of the TTRPG books it doesn't set out clearly what the PCs are actually doing in this world. Typical discussion of Tekumel often begins on MAR Barker backstory, talk about the non-Euro-American influences on the cultures, and the unique features of the alien world, but it hides what PCs may do in this setting or even how they would go about it.Aldarc is looking at this from a big picture perspective.
The Blue Planet RPG has one of the best science fiction settings I've ever read and it's absolutely filled to the brim with adventure hooks. But if I were to invite you to make a character for a campaign you'd have no idea where to begin. The campaign could revolve around a wildcat Longjohn operation trying to compete against megacorporations, a criminal gang in New Kingston trying to make their mark, GEO Marshals enforcing the law on the frontiers of a new world, or just about anything else that might strike my fancy. Whereas if I were to invite you to play a game of Shadowrun you'd automatically have a general idea of what the PCs as a group would be doing.
It's more of a design choice than a flaw I think. Blue Planet is a wide open setting allowing you to run a variety of campaigns right out of the box. But the lack of focus has some disadvantages a well. Just trying to narrow down what the PCs do can be a chore.
This is not to say that my grievance is with an abundance of lore. My grievance is with settings without clear play goals or expectations for GMs or PCs.
