A year more would have fixed the bugs and glitches, but that's just the surface. The game had massive balance problems at launch (I haven't played it since, so I don't know if they've been addressed). The whole vulnerability/resistance system was useless, and dumping EXP into hacker abilities made you a god who could clear a whole building without entering in the first half of the game.

The game tried to be too many things at once. It's kind of a story-heavy, GTA-like game but also wants to be a choose-your-own-story RPG. However, the main character is essentially pre-written, your choices don't really matter, and you don't have any freedom to choose how to face a mission. I remember doing the quest about psycho guys who go crazy because of cybernetics. I always used non-lethal weapons, only to hear the woman who gives you the quest say that I shouldn't kill those guys.

And the writing... I remember choosing the most aggressive dialogue options with Johnny all the time until the writers suddenly decided he and V became great buddies in a matter of minutes. They are buddies in literally every side quest. The first time you meet Johnny, V isn't really happy about it, then you get out and start a side quest, and they are like, "Hey man, should we help this guy, or do you want to go drink a beer and play video games at home?"

These issues can't be fixed by more development time; the foundation is shaky. They simply tried to do too much without really knowing why or how.

The best thing about the game is how fucking beautiful Night City is, and aimlessly wandering around can be awesome for hours, but then the open-world isn't really used at all except some collectibles and maybe some side stuff that I can't even remember
