Well taking the question seriously, here's my suggestions for what would fix the game for me both technical and otherwise:
Technical
* Keep supporting the Bug fixing and stability as best as humanly possible for as long as possible.
* Fix the Shard journal so that it remains "locked" in whatever way you left it. I'm annoyed I have to close every folder everytime I close it. Hell, it should be left closed automatically so its easier to navigate and find new shards.
* New Game+, you can have all of the cybeware appear after specific points in the game like Vic installing your stuff and you getting access to your stash.
* The ability to reset Attributes as well as Perks. Perhaps at a larger expense ala 10K.
* More V building options like visible cyberware (it doesn't have to make sense.
* Replace the scaled down adult animations for children with actually designed child animations.
World-Building
* Add the metro because so many people like it and I would enjoy the Disneyland ride around Night City.
* The fixing of the police system is good, definitely something very requested.
* Putting characters you can invite back to your apartments for one night stands. They don't need animated sex scenes but I liked the bit in the promos where they walk out of it.
* The option for purchasing gang-related outfits. At Lizzie's Bar you can purchase Mox paraphanelia, Maelstrom's bar, and so on for other gangs. I love the various styles of the gangs.
* The option for purchasing themes for V's main apartment ala Fallout 3. Like, learn to decorate your apartment Nomad, Corpo, or Street Kid style. Maybe even further with a couple of gang stles
* Car customization if at all possible, possibly restricted to a few vehicles at a specific location.
* The ability to download and listen to music at your computer or maybe a jukebox in V's apartment (replacing their surf board)
* The ability to download and watch all of the news programs on television at your computer or maybe buy a bigger TV.
* The ability to visit Clouds if you're not banned from it. Maybe get some more weird psychological profiles. Which I'm back and forth on given the lack of consent involved in the place.
Story based
* The ability to pay your rent. Which I think should be about 5000 eddies. It bothers me to no end.
* A Side-Gig where you pay to leave some money behind for Mama Welles after Jackie's death. Say, maybe 20K.
* More Gigs related to your Life Path. Not necessarily exclusive ones but ones you get a bonus for being related to.
* Some Max-Tac related quests.
* Some Trauma team related quests.
* More races, possibly ones in the Industrial Area and the Badlands and Southern parts of the map so there's more to do down there.
* Some more Mox related quests because I really love that faction.
Completely impractical Requests
* A second expansion set on the Crystal Palace.
* The ability to pay Trauma Team to save Evelyn (maybe 20K Eddies) and have her talk to V before abandoning Judy so not to disrupt the stories too much.
* The ability to have a hook-up with Maiko, Lizzy Wizzy, Blue Moon, or others because why not. Generally more one night stands in general (you don't need to have sex scenes).
