Well, I think I’l be writing some sci-fi this year, but I’m still not totally sure about my 2019 project. Regardless, I’ve written sci-fi in the past, and I think the FTL method you use should depend on your story. Rather than ask how the characters will travel faster than light, ask what FTL method will best fit your plot?
I’m an example person, so I’ll provide a few. Are spaceship battles an important part of your sci-fi plot? If they are, then something like jump points or fixed wormholes for FTL might work best because it limits pilots from just jumping out of battles they don’t want to fight. On the other hand, if the focus is more on the action that will happen on each planet/world, something like Star Trek warp speed that you can enter from anywhere as long as your ship is equipped might be better.
You could also split the difference and use Star Wars-style hyperspace where it takes time to calculate the coordinates and you have to have the right vector to jump out so your characters can jump from almost anywhere to almost anywhere, but it still provides some restrictions during space battles. That’s what I’ll be using.
Anyway, that’s just my two cents.
