No, the 2 IFs are a realistic point of view.
IF #1: The assembly of the parts still could fail, then they might release a game which is far away from what was intendended and thus bad.
IF #2: They are showcasing hand crafted missions which is absolutely great. The only way to keep a game interesting (just look how boring Elite's missions are. Repetition loop to death.) But! Hand crafted missions are time consuming and cost way more money. The question is, will they be able to do it in the long term or will they switch to procedurally genereated content (that's what FDev does and that what makes Elite boring and repetitive).
So, in the end, let's see. I can't judge before I see the final product and play it. At this stage, it's not possible to say it's gonna be hop or top.
You already know the answer to #2 It is impossible within the constraints of time and resource to hand craft multiple missions to the supposed standard of the Gamescom "double cross". You might get enough to play through something like Mass Effect, to give 20 or 30 hours of game play and then what? No more missions, as you have done them all. You could argue that works for Squadron 42 episode 1.
I think the problems of having a WoW style mission giver in a large instance multiplayer game have already been documented. Either everyone gets their own private conversation, regardless of how many other players are surrounding the npc, or someone "pad blocks" the rest, or someone goons along and murders the quest giver (Old Everquest trick).
The biggest challenge from a non-invested bystander opinion, is that as soon as you try and nail down one detail of how something will work, it opens up several other folders of questions.
As an example: If you can fly your ship to a comms array, can you lock the ship when you EVA? Answer is "yes, that is proposed"...
But your ship has permanence in the PU, so can someone else try and board when you are away? Answer "Yes, that is proposed, but they will have to hack locks or cut their way in"
But does that mean as soon as you leave your ship someone else can steal it or blow it up defenceless "Yes, that is proposed, don't worry though, you pledged for an LTI ship didn't you?"
Aieeee, my ship got ganked when I was doing my EVA mission, how do I get back to a shipyard to file my LTI claim and wait around for my ship to be built... This is the 4th time it has happened this morning and the delay is increasing each time unless I pay some UEC to reduce it... "you can wait for another ship to come along and ask them for a ride, or steal their ship to ride back to town...
I'm sick of getting ganked, can't I just pull the PvE / PvP sider all the way to PvE and avoid all this? Sorry no, we quietly mothballed that idea due to the complexities of nested slider settings in multi-crew, so man-up and git gud, commando...
