1) I think you'll be missing a few things from X - no cap ships you can park your other ships on. No player HQ, No player factories, no fleets you can command through a fast, effective interface, no wingmen,
2) ED has like 3 or 4 station designs and each of those come with a few color variations, but thats about all you'll see for now. Space is not handled like in X. Its both better and worse... Its better because its much more realistic. Its worse, because any real movement happens exclusively in "super cruise". You can't interact with anything, just move from here to there in a system. Whenever you drop out of super cruise, a small, temporary instance will be created, spawning a bunch of NPCs depending on presets for that location, and the game sets those NPCs to whatever relationship to you gets read from your character profile. Once you (and potentially any other players that were in that instance with you) hit super cruise, the instance ceases to exist. So basically, the game has one plane of movement, and any place you exit, you're in a wow style dungeon instance.
When I started to fly around ED, I went from "how the hell does this work?" to "omg this is awesome" to "ouch, this is getting tedious fast" within 2 days, due to the fact, that space flight insists you pay attention the ENTIRE time. No auto pilot and no real 'going straight for a long while' either, except when some station is an ungodly 30,000 LS from the sun..
3) Not that much fun right now, but only because game mechanics are very thin. A good foundation for future possibilities of better game play certainly is there. The star systems may be procedurally generated, but intelligently so. And adhering to current human knowledge of what types of star systems there should likely be.
Space itself is ED's great advantage. Its very bare bones right now, cause they're not funded like Star Citizen. But there's potential.
I would compare X to ED like this:
- X has a very poor foundation in regards to space, with those little EVE-like villages called star systems, but its filled to the brim with cool stuff and features and ships and things to do and really awesome whimsical races. (IDK about rebirth, didn't get that)
- ED has a really great foundation of space, but the price for it was instancing everything, and it simply lacks 90% of the stuff you can do in X.
Trading is the most worked out of the game mechanics, Mining and Exploration are rudimentary at best. Mining also includes a "catch the ore" mini-game which is the epidemy of game developer's incessant war on "sandwich fights", where you could set your character to do something or other and go to the kitchen to get / make a sandwich. Game developers somehow didn't understand that this is not universally a bad thing, but only sometimes. Braben apparently drank a lot of that anti-sandwich Koolaid and made every single part of the game require your full attention (which doesn't actually make it more interesting or fun in too many cases). In the case of mining, this results in such slow progress, even if you have become really good at catching the ore with your ship - manually, the only time mining can compete with other professions like trading is when you're still in your side winder, i.e. the first few days.
And there's Multiplayer - co-operative and pvp. Something that never was part of X, but will certainly appeal to those who like it. I'm not into PVP, but playing co-op with a friend is certainly a great option I wish X had offered. The multiplayer communication system isn't quite done yet either though. I'm pretty sure that's their next priority.
I can't complain at all about someone who is very ambitious for the level of funding they have. I respect shooting for the stars *literally*, defying budget constraints, figuring they'll get there somehow. That's more risk taking than Egosoft was willing to do, and so ED wins some, and loses some, and the final word isn't going to be said on this for a while.
4) You will be able to own as many ships as you want, but every ship you're not flying yourself will simply be rotting in storage.
As for convincing you to buy ED - lets just say that having bought the game already, I'd like them to sell many boxes, so they'll have funding to flesh out this game and bring it up to its potential.
I think I'll play it for a few weeks, maybe a month, and then take a break and wait till they get around to adding a lot more of the promised features...
I do worry a little bit about the overly harsh reactions from MMO players... like with SWtoR, which was brimming with features and story and things way above and beyond the going MMO standard (like companions, fully voiced and well written quests that told a cohesive story, different for every class) But all people could apparently think of doing was to speed through the levels and then complain about the endgame and especially some errors / bugs in the PVP endgame and then dumping the game for the next release of whatever. I thought the only regrettable omission was better space flight in that game and it recovered since anyway. I still like to play that one.
