It's no WCMC, but I've accidentally created the first Wing Commander FPS game! I altered a Darkening saved game to allow you to play as one of the games laser-welding space-men... and you can journey the Tri-System with your single laser and jetpack. It's remarkably fun, for something that has a top speed of 80 kps. Just put this file in your /dark directory -- it'll replace your first saved game. Load it up and... take on the universe!
