First of all: I like the game! I enjoy playing it and I neither regret having spent money for it (the game itself (starting with beta), a new joystick) nor will I hesitate to invest even more money (Oculus Rift, expansions, maybe even some skins). I am looking forward in excitement to whatever new feature FD will present us.
But still, I think there is something missing.
What is missing so far in repect to this thread, however, is not more shiny stuff. ED is full of it already. Athmospheric fligth, planetfall, walkable spaceships - all this will be highly appreciated and add to the overall experience for sure. But it will not change my personal grieves with the game.
It is neither multiplayer. Coop missions, multi crew ships, coordinated jumps... all of this and more will be great and the game will benefit from having it without any doubt. But it will not solve what I miss.
In my opinion - and it is only an opinion as good as everybody else's - the "magic" that is missing, the lackluster ingredient is the feeling of achievement.
Those who played 'The Original' might remember the struggle to reach the safety of the next spaceport under constant attacks of pirates. The anxious look on the sensors, the adrenalin rush whenever a groupe of blips indicated unknown spaceships approaching your vessle. Are they friend or foe? Will they attack or just passing you, minding their own busyness?
Transporting valuable haulage was a real risc! When you finally arrived at your destination, your hands might have trembled, maybe some sweat pearls stood on your forehead - but you knew that you actually had achieved something! Cashing in your trading profit was merely a sweet add-on!
Combat was forced on you! You had to withstand or perish! There was no "oh, do I want to fight or not?" mini game, no every-once-in-a-while interdictions. There were only laser-hits pattering on your shields!
And this was the reason, why you desperately wanted to upgrade. Why you were grinning from one ear to the other, when you finally could afford a better ship, a better weapon, better shields. Because it helped you to actually SURVIVE (and not just to have a new and "interesting" game experience)!
So, in my opinion, there is no additional content needed, to bring back the "magic" of the original game. All you need is already there! More content is welcome, of course, but will not change much.
What is really, really needed, is to bring back actual DANGER into Elite: Dangerous. A new... no, the OLD balance!
And with the danger, the feeling of achievement and sucess in overcoming it!
