A good idea to get some positve vibes flowing. (Or vibing? That sounds too adult toy-ish, doesn't it?)
The characters. Johnny F..ing Silverhand. Oh my god, what a guy.
I love the urge of the main storyline, and I actually like how the minor missions, 'blue' events just feel so mundane compared to the main storlyine.
Once again, the characters. Takemura, Wakako, Panam and the gang, our favourite Ripperdoc and Night City which is a character on it's own, and we are its bloodflow.
The atmoshpere.
The small things like the roller coaster, your cat, Mr. Nibbles, and minor details like you come accross a certain associate with a pair of concrete boots under water, all the side stories that are revealed through messages and thins you find by coincidence. How desperate the city can grow.
The music, the voice actors, the sounds in general.
I love the weapons, the clothes, that you can develop multiple styles.
The game is too easy sometimes even on harder difficulties but I love how you are not forced to one style vs another (like in the new Deus Ex games for example where non-lethal stealth gave you a lot of xp boosts so why would you go any other way)
I like just driving out listening to 'Night City', 'With Her' or any of the Samurai songs. I became a fan of a fictional band.
I like all the noise all the buzzing, even though it is make believe, it feels like a lot is going on.
The dialogues, even using the old (i mean the released in 1990 pen n paper RPG-old) slang it feels so much more natural than most of the games out there. They just have a natural flow to them, logging in to AC Valhalla after this just felt so artificial.
And the storyline. I didn't spoil anything for myself before getting started, and the rush of adrenaline on Konpeki plaza when a certain someone deals with another certain someone, oh boy!
I love that the whole architecture makes sense, the city seems like a natural, living breathing organism and locations, they make sense.
