I never said (wrote) that it is perfectly implemented. But it's THERE. In SC, you can DREAM about it. Yeah, CR, the Prophet of the the One True Universe, constantly promises stuff (flight attendences, mixing drinks for passengers, choosing music & movies, blablabla...). Doesn't mean it's ever going to see the light. One bird in the hand is worth two in the bush. Or, to stay in the proper lingo: I'd rather fly around in ED doing stuff that is imperfectly implemented, then being spoon-fed videos on what I MIGHT be able to do, once it's done (if ever).
Well, pirates and bounty-hunters don't exactly do the same thing, and, as I wrote above, it's not perfect in ED. But, again, WE CAN DO SOMETHING. I can flit through thousands of systems, if I want to.
ED may be a joke in some areas, but SC is funny. Not funny as in haha. Funny as in wrong. 'cause there is so little stuff that actually works. LOTS of promises, very little of which has made it into the game -- after five years of development. Don't get me wrong -- I'd be THRILLED to see SC released. Problem is, I don't see that happening any time soon. Maybe in three years. Maybe never. In the meantime, ED is growing, and we can actually play it without having to download 30GB every time the launcher is updated.
Again, I'd be thrilled if that happened. Kinda doubt it, however.
Saying that SC is oh-so-more-complicated than ED is like claiming that the mere idea (not even blueprint!) of a not-yet developed racing car is bound to be much faster than an existing racing car. It's no better than yanking out a hapless bull's entrails to predict what the Gods hold in store for us petty mortals.

My point being, SC is, right now, a skeleton. Muscles, nerves, tendons, skin, and organs need to be added. Right now, however, some people are still talking about the colour of the suit. That's what gets me going.
I slaughtered a couple of pidgeons and checked their entrails. Their livers were spotty, and their hearts shrivelled. According to these portents, SC will not be greater than ED, 'cause it won't even see release for the next three years, two months, six days, fifteen minutes, and thirty-three seconds. ;D (Sorry. I am NOT picking on you. Just an attempt to be light-hearted. I apologise if I have offended you (and, yes, I realise that not giving offence in the first place would be better -- again, sorry. I have to prepare my classroom for classes, and some . . . people . . . thought it funny to stack very heavy desks on top of each other. A lot. And I have a serious back condition that prohibits me from lifting heavy stuff. Which I had to. See why I'm cranky?))
Again, my apologies. I am not going to burn you at the stake for having your own opinion. I am, actually, happy that you have it and express it. I just happen to disagree. No harm, no foul.
Space Engineers is likely too much for me. ED was overwhelming, and it took me several weeks to half-way get the hang of it . . .
. . . I cannot say it often enough: I'd LOVE for SC to succeed and become a smashing success. However, I doubt that this can happen as long as Mr. "Let's refactor this until your noses bleed, and then some more" is at the helm of the project.
