I have to agree but there has to be a stopping point somewhere. The game is big at 60 and some GB but could easily have been 100 GB with the additions your describe. The game world is there as "fluff" mostly. The main attraction is "V", the story and voice acting. Then rest is just scenery and sadly so. I am not a big fan of mini games as a pass time while I am playing a game as a pass time, if you get my drift. I see no lure to stop for a beer at a bar then play darts. To make it interesting maybe script in NPCs that interact with V and it leads to another side mission or plot line, yes. But to simple play darts, no!
Well if V is the attraction its not a good attraction. The story is solid and Night City is beautiful (at night), but the city and Jonny Silverhand are more of a main character than V tbh. V was set up to be the player character that we could define. But in the end its just a pre-determined character that doesn't even get characterized that much, at least not where I am in the story.
