I've said this before and it's still my gut feeling: in the desire to hit the pre-announced December 16th 2014 launch date FD wrote themselves into a corner by pushing out a product that still contained much placeholder, with MVP code rushed into service to hold it all together. And while each subsequent iteration has largely improved on what came before -- some updates more than others -- the frequent need to push out new features to drive sales, as well as balance the increasingly asymmetric multiplayer aspects, has left zero opportunity to actually go back and rebuild the game's restricted core.
The more time passes, the less inclined I am to believe that this can ever be fully resolved. FD will no doubt add new features, or apply heavy reworking to some aspects such as the mission system, and some will be successful while others will fall by the wayside. But the underlying structure of the game is not going to change now. The economy will always be a giant everlasting firehose of credits with a series of BGS-adjustable taps rather than a structured simulation of galactic commerce. NPCs, beyond the static mission-givers and magic teleporting crew, will never be semi-persistent or interact with player characters in a meaningful or memorable way. The "solid" mechanic of exploration will always be jump-honk-scan, even if we get prettier things to honk at.
ED remains a remarkable technical achievement, presenting as it does a game world of such scale and beauty and, yes, immersion. But the way in which we interact with that world will always be hamstrung by the decisions made in 2014. Much of what was written in the DDA, hugely ambitious yet eminently achievable had the time been allocated, I believe will now remain firmly in the realm of what might have been, rather than what may yet be.
It's still a great game, still the best incarnation of David Braben's three-decade-old vision, and can still be terrific fun to play especially if, like me, you're old-school enough to appreciate its slightly retro charms. But it gives the appearance of having been rushed to release on very shaky foundations, and I fear those foundations just aren't capable of supporting the structures the game would need to reach its true potential.
I would never be happier to be proven wrong than to be proven wrong over this.
