There were quite many.
The Heist, the whole setup, how we get to know characters first, then to scene where we meet with Dex and T-Bug. It was phenomenal work. T-Bug there, voice acting and body language matching characters role and personality, all matching perfectly. That was the moment that got me thinking that this game might be something else.
Chandlerian evening or something. Noir was big influence to cyberpunk literature and I thought that it's just a name and it starts so subtly then Johnny starts saying few things... and I thought they possibly can't, this is too good to be true, but heck, they did it! Just amazing piece.
River's family, scene where we play Augmented Reality game with his sisters kids. I don't think I have seen anything like this in any game. Family dynamics and all that, in retrospect, that all build up a lot of other things in game.
Peralez. Powerful people, clever people and the whole setup, again voice, mocap and understanding that people on that social class, they express themselves differently, they think differently and that they are in a way also products of this world, having probably all surgery possible to influence their surroundings intellectually, economically and even sexually. That was great. I really don't care about conspiracy stuff, but as characters they really added new level of depth to game. It's easy to create luxury apartment to give impression of things but then characters are like powerful stupid or something, saying things way other people are saying in expensive suit, kinda why people stop playing games thing. But this was something else.
Brendan. One problem I have with cyberpunk is AI's and anthropomorphized AI's in general but I understand reasons why authors made them banks and hotels and taxi services for example. Brendan questline offered yet another insight to the life in the Night City. We can witness his influence and also how people react when he is missing. Dialogue options in the end, those really got me, like game was anticipating frustration and get out of difficult situation and come out like some ass hole really, but then there was option to back pedal and that was, huge. In retrospect, little things girl smoking a cig in relaxed pose chatting with Brendan and they appear to be having a good time. Whatever Brendan was, how often we ever saw anything like that in Night City. So it was somehow very important to be able to part ways with that girl on good terms. "...nicest person in Night City" a vending machine, yeah that too.
So many little things, walking around naked in nomad camp. Before assault overhearing conversation nomads have while they fix equipment in one of their tents. They talk about very different things than people in Night City, they talk about history, they are analytical and reflect that to where they are now. Noman education. Someone had this grasp about what all kind of things this world is about, and even before all the action, keep that grip, until the very end.
Endings, I really liked the endings. They delivered way beyond expectations. Could write short stories about those but:
Panam: Powerful, beautiful, V's life, there's window to fight for that but that chance for life to continue, and people can head canon that whatever way they like, what kind of person their V was, but for me that option for me V, leave that city, leave all that sociopathy and months, years, chance to grow the fuck up samurai, for different kind of responsibilities.
Johnny & Rogue. I'd just says it really completes character arch of people who aren't complete, perhaps never were to begin with. There is so much in there, but I'm just going to leave this here. Amazing writing.
Arasaki, with Takamura alive, I played that one too. It's very clever, it's very faithful to genre and it really was good use of horror elements and then you hear that the sociopath on top is back in game and you know, that he just ate his own kid, safe to say something happened to him, he wouldn't care who he eats. And all those people with their terrible barebones cyberarms you sometimes saw on streets, they have no access to this technology and they don't even know what's really happening.
It really comes crashing down to us, via everything we experienced, all we saw, through social classes what is power and transhumanism and problems of immortality. I'm very happy we didn't get some magical universe here and some stupid magical approach to transhumanism for people who like to use that word and think it's just another way to experience magic. No, this is cyberpunk.
