Love them or hate them there are a lot of common tropes across the science fiction genre. What are some of your favorite and least favorite tropes?
I think it goes without saying that one of the least favorite tropes is Deux ex Machina. I couldn't quite put my finger on it at first, but after watching the German TV show "Dark" I was utterly dissatisfied with it. The entire series up until the very last episode is about this inescapable time loop and alternative universes which is pretty cool while watching it, but then you get closer and closer to the end wondering how they are going to solve this impossible problem. Then surprise they just do it instantly in the last episode.
Another trope I am not very fond of is nanotechnology where there are trillions of tiny robots that can effectively act as magic. It just feels like a lazy way to write science fiction because you really want a fantasy.
A trope I do actually like despite how overdone it is, is the idea of a precursor or forerunner. It often brings to light the absolutely massive scale of the universe which I find fun to think about.
What do you mean with the idea of a precursor or forerunner?
It's a common theme where humans encounter some structure or evidence to suggest that some species or alien had existed millions or billions of years prior to humans. In Halo there are the forerunners that built the Halos for example. If you've ever played Mass Effect there are the mass relay's that humanity and other alien species discovered that connected large parts of the galaxy.
Before 343i and Frank "the terminal guy" O'conner was placed at the head of writing, the Forerunners were ancient humans as the original trilogy implies and directly states.
It was a cool twist that the ancients that left technology behind were actually humans that just forgot their own history due to the flood and Halo solution, then 343 just retconned the whole thing because they couldn't figure out how to make a new story that's actually compelling.
Well... Their actual story isn't compelling either but whatever.
In the current lore, Forerunners are most likely another species of hominid that evolved alongside humans on Earth and diverged millions of years ago. All records of this are lost to time, and by the time of the human forerunner war it had been forgotten. Forerunners are humans in an ancestral sense, but not in an ideological sense
Like the Forerunner civilization in Halo or the Precursor civilization in House of Suns. It's a long dead civilization that has tech abilities far beyond the current time period. So even though folks are zooming around in space ships they're intergalactic cavemen compares to those that came before.
