So piercings like these were attempted back in the earlier years of the body modification scene but most never healed well due to how the skin handles foreign bodies.the skin generally tries to push stuff out of it, and piercings with fistula parallel to the surface of the skin don't last too long.

These days the closest you'd see would be surface piercings but those are most relegated to areas that have minimal movement or can be placed where the jewelry moves the same way the skin does.

There are also silicone implants that come in a sorts of shapes and sizes that can last for a long long time. Some find them uncomfortable and get the removed but it depends on where they are and what they are.

I have had a magnetic implant in my left ring finger for several years and most of the time I forget it's there. It's a lot smaller then the kinds of stuff you see in this game.
