1) This could potentially generate conflict, because you're no longer talking about just a bit of chyen, but something people might use.
2) Ripper docs definitely need more incentive to obtain tools and engagement beyond the upper echelons.
3) The available items could be some low end common things. Pain editors, eyes, neurals or hardened neurals. Maybe an occasional hand, arm, foot, or leg, which are generally only supplementary and people have complained about before. Concerned about farming? Good news. Corporates are extravagant. Have the chrome pre-sculpted with some absurd nonsense so that the only people who will buy it are those concerned with function over fashion, and repeat solicitors of these products would end up looking quite monstrous.
I may have more to add later. Don't know. Back to life!
Or we could just add the thing I've wanted forever - a human bigmouth that blasts over SIC when someone's ripping their body. Preferably it'd be broadcast to either judges or corpsec, so they have to reclaim the chrome from past employees.
Okay calm down PT
...Why am I like this D:
I strongly suspect there is already vastly more used cybernetics in the game than there is demand for even an entire year of player character purchasing. Unless NPCs are landing with flashboosts in them, I don't see it making a dent in any direction good or bad.
I do like the idea of organ harvesting from the recently departed for extra chyen though.
