1. Population:
EvE online has over 5,000,000 Players world wide, and over 50k-100k logged in at any given moment. That's more then a specific Demographic. Having played EvE since Beta (recently quit a few months ago), I can say there are all kinds of people, who do all kinds of different things, from the questers, to the indy guys who build stuff to people who gather resources, to people who blow those people up, and other who own vast empires in nullsec and fight other vast empires, even explorers who go into wormholes and are not seen again for months at a time.
Battles of 5000+ individuals in a single system is common place. That's more people in a single battle on average, then the total number of people to play ED this week. So they must be doing something right.
ED has 5k players, maybe 10k players. (According to steam right now only 2k are logged in and only 4k have played it this week) Well say 15k total players to be fair and count those that don't use steam.
2. Vastness:
EvE does not have 4 Billion Systems true, but it does have over 100,000, which is pretty damn Vast, when Compared to ED considering the Vast majority of ED's pop is centered around the starting areas, because there is well... Nothing... Anywhere else. (Which is the main issue).
So Yea ED is Vast, a Vast Nothingness, with nothing to do in it's Vastness. Where as EvE is Vast with tons of stuff to do No matter where you go. See the point?
3. Owning space/etc
This is not an issue as the core where all the PP stuff is and the starter areas can't be owned by players, that's over 100k systems that players simply can't own and a vast area in and of itself. Problem solved. Not to mention you could always allow players to take each others systems and stations. (like EvE does). Not to mention you have Solo mode with ED where none of that really effects you in the slightest.
4. On Emergent content
If you don't like it, that's what Solo Mode is for. See, problem Solved, again.
ED is a Niche Game, Trying to be an MMO without offering anything an MMO offers. FD need to make up their minds, either keep it Niche and be small time, and see the game left in the dust in 5 years to other competitors, who take risks, and who went big, or Go big, and roll with the AAA MMO's and make a place in the Annals of gaming for the new century.
I AM NOT saying change the game GOD NO. I AM saying OPEN IT UP, and let players make use of the Games potential and Vastness like the Devs in their small numbers never could in a million years. For a game as large as ED it is simply FAR too much work for the Devs alone to create content and expect anything but the slightest fleeting success. No they need to let players create the content, and populate the Universe.
Do you really think for a second EvE would be the game it is today if CCP had said, Nope, Players can't do anything, heres 100,000 systems 75k of which have nothing in them but well get to them eventually and add stuff..... No, it would have flopped after the first couple of years when the Dev team got so overwhelmed they couldn't deal with it anymore. Or when the players got tired of waiting, got bored and left for other games.
So instead they created a sandbox (Like ED) threw the players in and gave them the means to control the Universe and said... Have at it. And they did, and now you have 100,000+ systems teaming with content where there is never enough time to do everything that can be done, and never ending content.
ED has over 400 BILLION star systems...... WTH is all that empty space going to be for? If you think FD plans for anything less then allowing players to do exactly, what they do in EvE, your nuts. ELITE Dangerous will be very "similar" to EvE in the end, just a Bigger, MUCH Better version of it, while simultaneously remaining it's OWN game. Watch.
Why? Because that is the only logical conclusion when you have a game this large, and this vast.
