These are tired old arguments and at least in the way you're trying to convey not true, and you're comparing it to ED?...
Here you are talking about personal tastes, and I have little or nothing to answer you to that; you like those things about SC, I think it's perfect (and it's not irony, I really think it's perfect and understandable). I don't feel the same way, but it doesn't matter.
But that's not what I'm talking about; beyond the fact that, objectively speaking, the few gameloops, the few locations, the few missions ("dynamic" or normal), the current AI, etc, that are in SC right now seem fun to you, the overall game is years away from the level of progression and "complete game" feeling that any game that is complete can offer. If I've given ED as an example it's because the videos that have brought this topic here now were referring to ED, but we can use NMS, Cyberpunk, RDR2 or any game you want; when you start playing a complete and finished game, you do it with the idea of progressing and advancing. If this game is an MMO you do it with the intention of progressing your character/ship/faction/etc... and if it's a story mode game you do it with the intention of progressing the main story of the game and enjoying the side quests.
I think it's unnecessary to explain the feeling of a finished game; be it an MMO or a story mode game.
And, beyond those basic core objectives, a finished game has a cohesion between all its playable dynamics; you do x thing that affects y thing, x thing you can do in different ways, you can increase your influence in the faction in x ways, and you can do this gameloop to get x things, etc....
Well, I repeat my idea which I think is clear; SC obviously can't offer that, and that's exactly what this player from the youtube videos is valuing the most, the "real and finished game" sensations that ED offers him versus SC.
Surely that same player (or any of us) can think and evaluate if SC's FPS mode is better than ED's, if he likes the mission systems more in one game or the other, if he misses the ship interiors in ED, or if he misses a functional and complex faction system in SC... but that's subjectivity in the different aspects, totally debatable... what is not debatable is that ED offers him the experience of a finished game and SC obviously doesn't offer him that experience. Can testing those things in SC be fun? yes, of course, but, as I said before, that fun is not going to be accompanied by the feeling of really advancing and progressing in the game. In SC you can only test things, with the clear idea that you're going to suffer thousands of bugs, and that nothing you do has persistence because of the wipes.
On the other hand, if you want, I can give you my personal opinion about all your examples, as the "dynamic" events in SC... but I can already tell you that they are very different from yours...
