I'd argue that the narrative space equal to a hyperdrive isn't a riddle or a puzzle, it's the magic. Both technobabble and magic are the same thing: fictional stuff that does stuff we can't understand.
I think this fits for certain "far future" settings, Star Trek, Star Wars, etc. It doesn't matter how the science actually works, even when they go into great detail about it on a regular basis, it's still essentially magic. Replace dilithium crystals with frogs tongues and you haven't actually changed anything.
But I don't think this applies to near sci-fi, for modernist post-apocalyptic, yesterday's tomorrow settings, those rely on much more "real" science, especially if they're centered around earth and the near solar-system. If you're more likely to encounter machine guns than phasers I think the game places itsself under a much more stringent sci than fi.
