Yeah! I think the Firefly example dialed it in for me. I know Star Wars also get called that, but both get sorted under “space western” in my mind, so I was never really clear on the exact use of space opera. Would things like Enders Game or even Dune technically count?? Like those are political dramas at a point. Enders game is maybe a bit simplified, but Dune has heavy character development with the backdrop of Arrakis and the technology required for survival.
