Cybernetics/Humanity rework:
The system as it exists feels cheap and tacked on, like changing your shirt, shoes or sunglasses. I do not understand why in a cyberpunk game the cybernetics feel so cheap- like we just didn't have time for this one. What else is there in cyberpunk?! The very first cut-scene with Vik Viktor is really awesome and I think most people would agree is fundamentally immersive. The problem is the game is inconsistent, as time goes on it seems like Cybernetics are less and less interesting/important, and less and less impactful. When we KNOW that it's suppose to be the opposite. The more you lop off and change, the more profound the change, the more tension with your fading humanity. There is ZERO consequence for chopping off your arms and legs, pulling out your blood vessels and even skeleton.
Suggestion: Have 3 stages like in the PnP game. Humanity 3, 2, 1. You can't go below 1, that's how you get cyberpsychos.
Stage 3 is after your first visit to Viktors. You get the awesome scene of him working on you, and you can access to a few cybernetics. Eyes, hand, and maybe a few others.
At Stage 2 you gain access to new arms (gorilla, mantis, rocket etc), and more cybernetic slots. You have some kind of cut scene here, and it's more involved, not just asleep in a chair, they remove your organic arms entirely. You never get them back. You are at Humanity 2, give some unique voice lines, a few unique reactions, perhaps your more vulnerable to hacks/malfunctions but nothing major needed.
Stage 1. You are almost entirely stripped of your humanity. You go through one more cut scene, it doesn't have to be long. Remove your legs and make modifications to your body. You take some time to heal. You gain access to the full range of cybernetics, everything. Put a cybernetic voice modification to all your voice lines to try and make you sound emotionless. Have some new reaction lines where people react with fear. Maybe effect ability to have relationships with some people?
What would you need to do? Add 2 cut scenes, add some voiced lines, modify Vs voice with software, add some reaction lines.
Cybernetic Items: The arms are neat, but each of them feel like they're missing something. Spruce them up a bit, make it worthwhile chopping your arms off. In general take a second pass at the items and see what can be done to make them more interesting and interactive. Perhaps have some of the other cybernetic items make cosmetic changes like the arms do.
This on the whole would bring the game closer to a roleplaying experience and address some of the central themes of cyberpunk, you could do very little and have a great shift in the feeling of things, or you could go crazy and create a lot of depth here. Maybe the HUD gets crazy the further robotic you go, maybe your become more suseptible to hacking, maybe not.
It also adds great replay-ability. Which seems kind of lacking in the base game. It seems underveloped, I think this is the one thing you need to NAIL, you really need to get this one right. I feel like it needs improvement, and I have to imagine that a lot of the ideas devs had for this one never happened because of time constraints, I'm sure there was a vision that was better and more complete then the one I've laid out. Put it in, people will respond to craftsmanship.
