Firstly, I love this game.
Secondly, TLDR: I agree with OP.
Potted History: I'm middle-aged. In terms of the Elite franchise I'm old school - Elite on the BBC Micro and Amiga & Frontier:E2 on the Amiga, although never played FFE because I didn't have a PC at the time and by all accounts it was an unfinished & terribly bugged game.
When Elite Dangerous turned up I was really excited but by then my gaming was solely on console and my PC was reserved for work so I watched, intrigued and slightly jealous, as it developed until the day they announced the PS4 version, when I realised I would eventually play it. So I've only been playing Elite Dangerous since last spring, and I probably haven't had the time to get as salty as some of the original KS backers and other PC players.
...BUT! ...One of the things that does bug me is the amount of time some actions in the game take. Unnecessary amounts of time IMHO. There are examples of this throughout the game.
I do get that there's a 'sim' aspect to ED, and I love the mixture of real science, pseudo-science and sci-fi science that's used to achieve that. I love that the Milky Way is huge and largely accurate to current knowledge. I love the way that the FSD works is based on the theoretical physics of the Alcubierre drive. However I've been doing a lot of exploring and charting systems lately and just in that one aspect of the game there are two good examples of unnecessary time wasting that I feel get in the way of my enjoyment in that they 'interrupt' my focus and immersion in the game.
The first is the time the scanners take. Yes, I get that it's nice and sci-fi feeling to have things (like the FSD) charge up, or spin up, or take at least a little time to work - but the surface scanner (for example) takes between 15 & 35 seconds to complete a scan depending how far you are from a body. As far as I can tell those are arbitrary values made up by FDev, nothing to do with the time it takes the game to retrieve the information. When you're scanning a system of possibly 20-30 bodies or more that time adds up, and it's pretty much time spent doing nothing but staring at the screen waiting for the scan to finish. That's without factoring in the time travelling between bodies, which is the second thing...
Yes - mentioned before in the OP but - one of the biggest, most intrusive, and inexplicable time wastes is the amount of time spent in SC travelling anything over a few thousand light seconds. Sure there's an emphasis on achieving a certain sense of realism in Elite Dangerous, but come on it's still a game. I can't fathom the thinking of any game designer who thinks it's acceptable to leave the player sitting staring at the game screen for 15, 20, 30 minutes or more with no interaction apart from watching some space dust streaking towards them and keeping a check on a rolling digit counter. I mean... think about that for a moment. Seriously. That's not an exaggeration, you can quite literally sit in front of your computer monitor or TV for 20 minutes doing nothing. My girlfriend thinks I'm mad I'm sure. She'll ask, "So what are you actually doing in this game?" ... I try to explain and I'm sure it just makes her question my sanity even more.
It wouldn't take a huge change to reduce SC travel times either, all they'd need to do is change the acceleration and deceleration values of the FSD so that the ship reaches higher speeds in the middle of the journey, that would help a bit at least. Otherwise they could maybe introduce a mini-jump mechanic for travel between stars in the same system or something like that, I dunno.
Either way, there's a lot of time spent in ED not actually 'playing' the game, and when many players have a full and busy RL and limited time to play, that's a crime IMO.
