Eve is the king of the space genre, and has been since its launch. All Elite has going for it is the flight model. And maybe its detailed stations. The perfect space game would be Eve mechanics combined with Elite FPV and graphics.
Some very popular games just don't appeal to me, like EVE (and WOW)
What do you think of Infinity: Battlescape
Gained funding in December of 2015, looks great, can't find a projected release date?
My point is that there are many sorts of space games. Each one specialises in different aspects but has a certain structure. But most imitate the same space multiplayer activities in sandbox: trade, combat, build, explore, survive...
Space Engineers and Stationeer work on construction and management.
Elite Dangerous, Star Fighter Inc and Star Citizen and Infinity Battlescape are spaceflight simulators.
Eve Online, Hades 9 and Dual Universe are interactive MMOs.
Stellaris and Everspace are grand strategy games.
No Man's Sky, Hellion and Osiris: New Dawn are extraterrestrial survival and exploration games.
X4: Foundations is a corporation focused game that continues the X series.
Some of these games I have mentioned are still in alpha. They look interesting and promising but some won't make it. Space games are a lot of work to do in creation.
So far I know of only Star Citizen and Dual Universe that ambitiously wants to make 'the most complete space game' for all space gamers such that it won't need further improvements after release. But to me, the top space game now is ELITE: DANGEROUS!
So true - many different games for many different player styles.
There is a lot of overlap - for instance Dual Universe is like Space Engineers while also being massively multiplayer, and unlike Eve you can fly your ships from the pilot seat (I believe)
And while NMS can be a survival game, you can also pilot your ship into space, accept missions/quests from NPCs, and join in Space mining and combat.
But of all the games which are playable today and allow you to pilot your own ship, Elite in my opinion is the most fun, in large part due to the multiplayer.
However, that could change in the coming months.
