never thought of it like thatEver since the game came out there's been a lot of discussion about whether the endings are satisfactory or, indeed, happy enough.
But I do think the mood you get from them varies depending on your engagement with the wider ideas presented by the game. If you explore, if you engage with a lot of the lore, a lot of the game's content is exploring questions about the nature of the soul and of consciousness (even the Delamain quest ends up as a conundrum on sentience and the nature of life).
In that context one of the themes that recurs repeatedly in the game is Buddhism. At a superficial level, walking around you will see monks from time to time, there is the temple, and so on.
More importantly, there are the meditation quests (which provide a neat bookend to the tarot quests, the one dealing with stepping beyond existence as interaction of the self with the material world, the other dealing with questions of predetermined destiny versus freedom of action).
The game, I suspect deliberately, but possibly by happy accident, skirts very close to exploring the Buddhist concept of the non-soul (see https://en.wikipedia.org/wiki/Anattā ). Essentially (VERY essentially), there is no such thing as a soul, human consciousness is ephemeral and transient, the self is not a thing distinct from anything else, that there is no self as some kind of island but only the possibility of enlightenment that everything and everyone is part of the same machine.
Such themes do lead to a very different context in which to receive the endings than "I like this person why can't I be with them", including, as it happens, the shortest of all the endings.
I don't know if this is interesting to anyone but, well, it struck me as something to mull over. It's what makes me think much of Cyberpunk's storytelling is like almost nothing else I've seen in a videogame.
