I'd concure it's well worth the money I've spent. 8 hours a day, 7 days a week for the first 4 months equals nearly 1,000 hours of play. Divided by the $60 for the game, $60 for a hotas and monthly fee of only $13.00 for the online conection fee via ps+ (50÷15 (sales promo price)) that works out to be only about $0.13 per hour. And though I've not played in a few days, I will agian after the new update supposedly in the first quarter next year. Making it an even better deal.
Presently I'm looking for a game such as ED, that will keep my interest but closer to NMS which has considerably less need for combat. More on the line of MYST and other's simular to it, would be great.
As i'm always saying, Egosoft's X series is brilliant, with its' only real problems being that it's PC only (well, it's developed first for Windows PCs with most of the games in the series have been ported to Mac and Linux, but they're all still PCs) and the fact that the most recently released game in the series and its' only so far teased sequel aren't "real" X games but still, in particular X2, X3: Reunion, Terran Conflict and Albion Prelude are brilliant, while the newer game Rebirth has its' fans but not too many (while the first two games in the series are still playable on modern PCs, they look very basic now).
(While i've posted long posts about X in various threads, but in particular read my now hidden behind a spoiler warning summary of the entire series on the following page:-

As for games more like Elite or those that do certain (or many) things better than it, short of X or if it ever comes out at all, Star Citizen, ever coming to Playstation, you mentioned already you've already played No Man's Sky, but for other games in which you either fly space ships or simply have a space setting...
First on proper space games:-
Rebel Galaxy is really good and basically Elite-lite, with a similar gameplay structure of little to do beyond buying and doing up ships, though it does have a story and trading in it, they're not too deep and you'll get though its' campaign in 20 hours or less while even if you haven't done them up, you should have the money to buy the biggest ships in the game in that time, or maybe in 30 hours at a push.
The one real oddity about it which you should pretty quickly get over is that you only fly large ships on a 2D plane, flying and fighting in them mostly like they're terrestrial Naval ships in space and though the game does have smaller fighters and gunships which fly around in 3D, the game won't let you fly them, though that gameplay is ripe for an expansion (which we'll probably never get).
The game was free on Playstation Plus close to a year ago, but even buying it now, its' not dear, having only come out at €20 and often being offered on sale for €5-10 since.
Star Trek Online and Dreadnought (with the latter still only being in Beta) are both free to play and both well worth playing.
While Star Trek Online has existed since it originally came out on PC in 2010, it's been expanded a lot and supported with lots of patches since it came out on PS4 in September 2016.
It features mostly space combat and exploration, but also on foot, third person gameplay as well, though its' ship gameplay is its' highlight.
Dreadnought then, so far only has players fighting within the atmospheres and low orbits of planets, and will likely never get more than combat based gameplay, but the style of its' ships is well worth checking out, even though i know you're not really into combat
.
(While its' combat isn't too taxing and you're given new ships to fight in each time you spawn. Also you COULD focus on being a healing or other support ship only...
.)
Lastly, while they're not spaceship based games, but only space set games, you might enjoy, in particular the style and possibly the gameplay of Warframe and Planetside 2, both of which are free to play.
(We also had Dust 514 on PS3, but its' servers were shut down in May 2016, though it's a pity it never relaunched on PS4...)
Lastly we're still waiting for a proper Worldwide PS4 release of Kerbal Space Program, after a version only initially came out in North American regions in July 2016 and that release was so bad it was eventually pulled from sale.
Though a lot of the original versions' problems were blamed on the company porting it and a new company is porting the new version and they seem to be intent on squashing every bug in it before it gets a proper release, but it's expected to come out
soon, likely at a reduced price
