This is the NMS thread of the hour so I guess I'll just post this here as well in regards to people's expectations versus what Hello Games has shown.
If you pay attention to how Murray has phrased things, it becomes apparent we've already seen much more of NMS than Hello Games ever wanted us to see before its launch. A lot of that has probably been Sony's doing. Hello Games originally wanted NMS to launch with less fanfare and hype than it has currently gained. Murray has referenced the first person survival games that kind of just appeared on Steam out of nowhere and got popular. This also leads me to believe Hello Games is still deliberately hiding significant details about the game's systems, where any publisher launching a AAA game would have given us incredibly in-depth previews and shown us all the menu screens at this point. Sony may be hyping the hell out of NMS, but Hello Games apparently doesn't want it to be anticipated in quite the same way as a AAA game at this point.
Some have taken this to mean NMS is going to be less than what is currently anticipated. Personally I think that really means it could go either way. How much did we know about Elite Dangerous in the months leading up to its release? I ask because right now we have still seen basically nothing regarding how the in-game economy will work in NMS, how you'll buy ships, the menu screen where you'll buy and sell commodities, the table of elements, etc. Murray has just mentioned those systems in passing but he seems to want to keep them all mysterious so people can just discover all that stuff when the game actually comes out. That could either mean he's just being mysterious and those things are actually really well-designed, or that we'll be disappointed.
Another odd little tidbit -- almost every planet Hello Games has shown us has been a lush world filled with life, but Murray has said multiple times that 90% of the planets in the game will be lifeless rocks or deserts. Of the 10% that do have life, only 10% of those will be the lush worlds we see in the videos teeming with complex life. So really we've been seeing almost nothing but the 1% most interesting planets so far, if Murray is to be believed. I can't remember where he says the number of planets each system will have but I think the maximum was around a dozen, so it might be that every system or almost every system will have one planet with some life on it. Edit: I actually just remembered something else -- the universe we're seeing in some of the trailers isn't the one that will be in the final game. Murray did say that Hello Games plans to sort of "re-roll" the algorithm and procedural generation upon launch, so maybe the spread or proportion of planets will be different in the final version of the game.
They already said the game will have no quests at all. You'll never see an objective screen or whatever. There's literally just the players, the world, and things going on in the world having repercussions.
So, instead of a quest, you may just come upon two factions fighting and decide to get involved, and have the results carry on from there. One side might become hostile, the other friendly. Maybe there will be other details they haven't shared with us yet, but Hello Games already confirmed there won't actually be any "quests" in the conventional sense.
