What are some games which primarily display wireframe graphics, or at least have parts with wireframe graphics in them like the cyberspace sequences in System Shock 1? I want to feel like I'm a hacker in the 80's, flying through cyberspace fending off abstract representations of security measures. I tried the demo of this cyberpunk dungeon crawler called Der Geisterschiff which was released recently, which really nails that aesthetic (and gameplay) without going into Virtual Boy territory.
