Would you say it's a standard space opera aesthetic (like say Star Wars) or do you feel the era Traveller was created in was sort of different there even with space opera looks?
I guess to me, somehow OTU 3I's looks remind me of Buck Roger's (1970's version) or old Battlestar Galactica.
But what's weird is that I'm completely fine with Star Wars's aesthetics despite the fact it's from the same timeframe. Well at least the Original Trilogy's looks were from that era.
It was (and, aside from GT and MGT, is) an Aesthetic of the 60s and early 70's space opera.
Life is common; intelligence isn't, but intelligence spreads; FTL is hard until it's achieved, then easy to replicate; robots are rare and dumb; AI is hard; FTL communication is by sending ships.
Star Wars is a different mode. Life is common; intelligence is near inevitable on life bearing worlds; FTL is merely hard, but is also cheap, and is natural to develop; robots are capable of full AI; FTL communication is via FTL radio.
Buck Rogers TV show (with Gil and Erin), in the same terms: Life is uncommon; intelligence is rare, but spreads; FTL is very hard, using gates and hyperdrives, and expensive; AI is hard but doable in small packages, and many robots are AI driven; FTL comm goes via dedicated FTL comm networks at real time. FTL Navigation seems hard, and FTL drives are apparently huge; this makes stargates preferable.
Old BSG: "Life is uncommon, but was spread by humans; Humans are everywhere, but are not the only intelligence, tho' others are rare (We see only 3 non-human intelligences in oBSG: Cylon, Ovion, and the ascended in their ships of light); AI is hard, and anti-human; FTL comm is known and real-time, but STL comm is still available; FTL drive is obviously possible, but not discussed.
Both TV Buck and oBSG have visual influences from Star Wars, but harken back to the 60's SF in many ways. And, of course, TV Buck also has influences from the old comics and movie serials. And it's an important difference from Star Wars: Moralistic. Star Wars Assumes a fixed external morality (imposed by the Force), that makes it's morality black and white, and thus no need to preach it. oBSG was a weekly morality play - make the right choices, and things work out. TV Buck Rogers was Nationalistic, more than moralistic, but from many of the same creatives as oBSG, with Earth as their "nation"... it replaced the Han of the original Armageddon novel with the Draconians, a human culture separated for some unspecified time, and with slightly higher tech in some areas, but lower in others. And the Draconians are cruel, dictatorial, and a "clear and present danger" ...
The original Buck Rogers novel was quite different... it was (1) earthbound, (2) had the Han as the enemy - a Chinese empire writ large, (3) about asymmetry in warfare, (4) did have "non-radio" radio-like "ultraphone" comms.
All of them have gravity manipulation, tractor beams, and zap guns of various sorts, tho' Traveller's are much less portable in the playable tech range.
I cannot speak fairly of nBSG in these terms, as I found the initial changes sufficiently "Not at all what I was expecting from the Brand" that I disliked it, and thus didn't watch it. (And when I gave later episodes a try, it was moreso.) What I can say is it's much more morally gray than any of the above, and for me, that's a HUGE turn off. It has FTL, FTL real time comms, and FTL is big enough to not be on small craft, and AI and robotics so advanced as to be indistinguishable from humans on a casual medical inspection.
