There'd certainly need to be rethinking of both game balance more generally and ship builds, to ensure that attritional damage was manageable, but this is what I mean by the difference between Elite/FE2/FFE and Elite Dangerous.and taking damage in the fight could ruin whatever you were trying to do
In Elite/FE2/FFE the encounters between you and the station pretty much are the game. If you take too much damage getting there and have to retreat, that's why they were there in the first place. If you take a mission to bomb a military installation in FFE you'll be fighting military patrols most of the way across the system, with no greater reward for beating any particular one than "well, now I can get a bit closer to the target before the next one finds me". Actually bombing the installation when you get there is just a case of launching a fire-and-forget missile, pulling away while it drops on target, then hyperspacing home: most of the actual action takes place long before that point.
In Elite Dangerous it'd be balanced very differently: bombing the installation would be a complex process with lots of use of hatchbreakers and recon limpets to expose a particular vulnerable point while avoiding or defeating station patrols and weapons, then fire in some sort of explosive and retreat before it detonates, and then maybe repeat this process a few times on different spots to build up the structural damage, then watch a fancy explosion as it breaks apart and maybe have some salvage opportunities ... and so things happening to you on the way are just fairly boring filler [1] if they happen at all.
So ED has changed to a very destination-based gameplay compared with its extremely travel-based predecessors but retains the "travel takes a long time" aspects of its predecessors even though nothing can really happen on the journey and people tend to object when it does.
[1] The other difference is in outfitting. In the previous games any mid-sized ship (not even necessarily as big as the Cobra III) could be outfitted as a "do anything" ship. So it was pretty much guaranteed that you'd be ready for anything that happened along the way. ED is very much - especially nowadays - designed around "a separate ship for each job" with much more limited scope for multirole builds especially on the smaller models. So in FFE a few patrols coming up to you on your way to the installation, no big deal, you've got weapons and shields anyway. In Elite Dangerous a few Glaives showing up on the way to the Titan ... well, this is your Titan-attacking ship, not your ship for fighting Glaives/Basilisks/pirates/etc and let's not even consider what options a mining T-6 might have.
The really extreme stuff I never visited much anyway - but I do miss the mid-sized craters. It's just not a terrain type which appears much if at all in Odyssey and driving from the rim to the central peak of one used to be my favourite "mess about in the SRV" activity.Mt. Neverest and the heavily ridged bodies, I remember those... Can't honestly say I miss such extremes, but they did add character.
