Me personally, I'd rather have one form of FTL only - hyperspace, with the ability to pop out wherever I want in a solar system. I'd also prefer a much higher cap on top "real space" speeds - say 0.5 C, and have thruster size affect acceleration rather than top speed. For the sake of combat, there could be speed restriction zones around stations and other areas where combat might take place (something that works similar to a permit lock but for thrusters).
Supercruise in ED is way more magical than artificial gravity. Even if we could travel faster than light in this fashion, we'd not see anything outside our windows except perhaps a psychedelic light show. Hyperspace (which I consider a space-folding or wormhole-generating technology) feels much more realistic to me. Give me The Expanse with FTL and that would be great.
If we could pop in and out, from point to point, all over the place, with the hyperspace mechanic, then that would really degrade the experience of space travel.
As far as I am concerned that would be a disaster for the game.
I think Supercruise gives you the sensation of space travel. I still think it is awesome and a thrill to swoop around planets, soar past a beautiful star or planet, and I must have done it thousands of times by now.
I love supercruise. It is a magnificent addition to this spacesim.
It is the perfect balance between extremely fast spacetravel and still being awed by the enormity of the universe.
SC also offers possibilities for added gameplay.
I would welcome limited in system mini jumps though. So there would be a minimum distance you can use in system jumps. This would be useful in very large systems.
But there could be other limitations to. Just to make it interesting.
I made a proposal long ago:
I would like changes to supercruise.
CHANGE 1.
I want more player agency. I want to have more influence on flying in supercruise, more piloty things to do.
This could be done via pip management for example.
CHANGE 2.
I also want the HUD to change its layout in supercruise with new HUD elements, just like it changes when you approach a planet.
I am sure FD could make something up to make it look cool and different and appropriate for Supercruise.
CHANGE 3.
I would like to be able to do in-system mini jumps to other stars in the same system.
There could be rules for this to be possible:
1. A second star has to be at least 50.000 ls (just an arbitrary number) removed from the main star for example.
2. You might need to fly 1000 ls away from the main star to be able to do a minijump
3. Minijumps might cause light damage to the FSD
4. Minijumps might consume a lot of fuel, because... reasons.
5. We might have to buy an expensive modification for the FSD to make minijumps possible.
6. Minijumps might not be possible to certain star types.
7. Some far away stations (for example military installations) might have jump inhibitor technology to prevent ships from jumping in via mini jump.
