This can be anything from Hyperspace in Star Wars, Warp Drive in Star Trek, travel through the Warp in Warhammer 40k or anything else.
I’ve always liked “slow” FTL travel, where going a few light-years still takes a few days or so. I also really like travel through an alternate dimension like in 40k, Event Horizon, Witchspace in Elite Dangerous.
I wanna know your favorite versions, or do you prefer stories that obey the laws of known physics, like the Expanse or Rimworld?
I like the Stargate-lite system in the game Terminus (2000). Unlike Stargate, each gate connects 1 to 1 with another, so there’s no “dialling up” a new destination. In fact, these gates don’t go anywhere unexplored. They only go where we’ve already been (around the solar system).
See, in Terminus the space ships can only fly at realistic speeds (similar to real life rockets) and maneuvering is difficult (with pretty decent Newtonian physics). If you want to travel to other places in the solar system it takes an extremely long time, so the gates make it actually feasible to get around.
This all had the effect of making space feel like the age of railroading. You can get around but you’re limited to where the rails can take you. I don’t know why, but there’s something so romantic about that.
