Finished the game late last night. I think I clocked in at about 60 hours. I did every side mission available to me, except the collect-a-thon ones like the tarot cards, and a bunch of gigs and open world missions. Easily one of the best games I've ever played.
I really can't get over how much they nailed the look of the city. Just in awe of every street, every tunnel, every building and the map and city are so intricately designed it's mind blowing. It looks amazing during the day and at night. CDPR just nailed that 80's early 90's sci-fi feel; this world would slot in perfectly next to Akira, Blade Runner, Heavy Metal (that part with the cabbie), Cowboy Bebop, etc. It's just perfect.
The gameplay exceeded my expectations as well. Usually first person melee combat sucks but I had a blast with it in this game. Also revolvers are the way to go for guns, since you can hip-fire with no penalty and the heads just pop!
Played on xbox sx and had minimal problems with bugs and only a couple very minor things after the most recent patch. So hats off to CDPR, this game exceeded my extremely hopeful expectations.
