Incidentally, playing the game I was never given the assumption that V *could* be saved, but that it *might* be possible and probably *wasn't*. The only clear route was Arasaka, whom it was clear we couldn't trust. The Alt route was ambiguous and always struck me as presented as "we can try".
Also incidentally, the approach to endings seems to be polarising people as much as something like Alien 3 (the ending of which, personally, I love).
Sure, it's like Lord of the Rings, the overarching objective is to destroy the ring but, for the characters, it's very difficult to do, their chances are extremely low, etc. But as an audience we're made to expect that the matter of the ring will be resolved by the end of the story because that's how the whole thing is structured and that's what all the plot threads are converging on.
With Cyberpunk77, Its kind of interesting to me because while some of the endings do feel final and resolved, the Star and Sun endings don't, and leave the story's main premise feeling incomplete and vaguely-cliff-hangery. Which I'm fine with if I know that this is supposed to be part of a series or a trilogy or whatever.
But with CP77 I'm genuinely unclear on what CDPR's plan is supposed to be. Like, are they planning to resolve it later or was that supposed to be it?
I'm still thinking DLC, because of those hints (like the one you mentioned), but we'll see I suppose...
Come to think of it, has anyone actually asked the writers about this?
