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?

Allister Reynolds: Revelation Space universe. Its not FTL its near light speed with time dilation as an actual plot device. The only hand waving part is the power/device to get up to speed, but everything else is in the realm of physics.

Also love how (minor spoilers for Redemption Ark follow) FTL travel is possible in the universe, just so hard to do that if you get it wrong you're lucky if it only blows up, rather than fucking with causality to the point where you never existed

Not only was it incredibly difficult (required sacrificing actual human minds for the calculations) and insanely dangerous (like that one tech who was at the wrong place and time of an FTL anomaly and every particle in their body vanished from all points in space/time), but the actual gain over lightspeed was only like 1% (the FTL ship was traveling at 101% light speed, chasing a LightHugger traveling at 99% light speed).

I hope Revelation Space gets made into a show one day, with spin-off movies (Diamond Dogs for example) and webisodes (daily life of an Ultra).

You just reminded me of the bit where they discover that fucking with causality is BAD.

spoilerThe poor scientist who is the only one who remembers their friend existed. As well as the lead who is left wondering how many scientists he accidentally killed.

I love his books.
