I'm sorry, but you are just wrong: MWO is not an MMO in any shape or form. What unreliable Wikipedia says backs-up my vague impression, which is that it's 12 v 12 arena combat. i.e. Basically a multiplayer FPS like Battlefield or whatever, except with huge mechs rather than puny humans, where the networking technology isn't much different from that used in Quake 3 Arena (released in 1999). That renders the rest of the argument irrelevant, so I'll only answer a few bits.
It is 12v12 arena combat in MWO while ED has a 32 player + AI limit in an instance. Functionally, an instance is no different from an arena with join in progress ability. Join in progress has been around forever. They claim it as an MMO and the definition of what an MMO is is so loose I see no reason to argue it.
ED doesn't have any technology which hasn't been done before by someone else, but it's *combination* of technology is absolutely unique as far as MMO gaming is concerned. So unique that quite a lot of people have difficulty accepting it as an MMO (comparing to existing MMOs rather than looking at the definition an MMO), and also people often insist that Frontier need to add features from existing MMOs (such as guilds) that simply don't fit into the kind of game that David Braben is trying to create.
Mind pointing it out? Honest question cause I've seen all this stuff before aside from the planetary orbits. Some of it hasn't been in games considered MMO's (such as joystick support) but the p2p system moves it more into the traditional SP/MP game arena. And that has a long history of joystick flight. My first online combat flight sim was IL2: Sturmovik back in 2002-ish. It supported 32 player servers and could be hosted by basically anyone with a DSL connection. It wasn't the first either, just the first I bothered playing online.
Sadly ED has been rushed for release before it is ready, many features only exist as basic 'placeholders', and multiplayer communication is one of them, which makes it even harder to explain to those people how ED is a different kind of MMO to any before it.
I agree it is lacking the depth they promised in the DDA's. Smuggling has been reduced to crashing the docking slot as quickly as possible, piracy has been reduced to filing bug reports and being told it's working as intended while the dev on the forum says it's a bug and to report it (no joke, see the piracy threadnaught), trading still doesn't have even the most basic ability to record prices of visited stations or view them remotely and so on.
A lot of people backed ED's Kickstarter BECAUSE it offered a vision of a massively multiplayer (space) game unlike anything else.
Sadly that isn't the impression I've gotten on this forum over the last 5 months. A large portion of the community here immediately tries to shout down anything related to multiplayer.
You will see that I started a thread listing features that ED needs before release. And I have commented in other threads suggesting similar things. So I agree that ED is being released too early. This wouldn't matter, except that reviews will be released, and I very much worry they will give a bad first impression. (You can imagine them giving all sorts of praise, but then going "but you will spend half your time in SuperCruise, which can get really boring" or "but you can't easily chat & meet-up with people".)
So oddly enough I actually agree what you think needs doing to ED before release. You appear to have jumped to conclusions about what I think, based on what I said bearing a little resemblance to what other people who disagree with you said.
That's my concern too. I've already paid my money so if I have to wait another 4-5 months for a working game, it doesn't really matter. The problem is if it's fixed then but all the reviews have given it a 2/10 beforehand, there will be no one here when I come back and no future expansions. In any case, the reason I assumed you were one of *those* is because of your claim ED is doing something different. I just don't see it. The only thing that's different about it is being a space flight game. Which I'll admit is rather different to a lot I suppose, but coming from DCS, RoF and BoS, this is just my usual stuff.

I'm also all too familiar with waiting 5+ years between titles of the same genre.
