Lets talk about Thief: The Dark Project PC

The Dark Project is the latest first-person gaming experience from Looking Glass Technologies. Featuring a full 6-D engine, raycast lighting, realistic physics modeling, motion-capture biped movement, photo-realistic textures, and our unique "Act/React" environment simulator, Dark brings you the next generation in computer role-playing simulation. In Dark you play the role of Garrett, an unrepentant thief in a vaguely medieval city of decaying streets and decaying values. Rather than killing everything in sight, you need to use stealth, surprise and cleverness to achieve your aims, as you move silently through dark streets, mansions, and catacombs. But behind the crumbling facade of the city lurk opposing forces locked in an ancient struggle for dominance. Caught up in the conflict between them, you need to develop new skills and improvise new tactics to survive, as you stalk your enemies, set traps, and engage in combat with man and beast.
