Agree, although Blade Runner has got very limited relevance to the other 2, not sure how you synthesise.
I could see the Jedi as a Dune-style Ancient School, with toned-down powers and no lightsabers, and the Sith as an offshoot of corrupt mercenaries.
It definitely had light sabres under a different name and did telepathy using much the same spell-lists system as Rolemaster, although there wasn't a direct knock-off of the force. You could do a pure telepath or hybridise it with other classes for something analogous to a semi-spell caster class in Rolemaster.
You could see Blade Runner's influence in the eugenics and replicant species, of which there were about half a dozen of each but not so much in the setting. There wasn't much of the cyberpunk or blade runner vibe in the setting, that was mostly a knockoff of the great houses of the Dune 'verse. Really it came out a few years before cyberpunk really started trending in sci-fi literature. It does give the distinct impression of being written by serious Dune fanboys.
There were a few odd traveller-ism's here and there; the authors had obviously read if not played it at some point. Looking back at it, I get the impression that it was designed to be not-Traveller. Many of the OTU conceits like tech levels, short jump ranges and travel-as-communication were obviously rejected.
I'd rate it about a B or B+ in the grand scheme of things. It wasn't crap, and it almost made it as having some atmosphere (if more than a little derivative of Dune) but it wasn't great either. Sort of a near miss.
