Thief: The Dark Project 1998

Is it still worth playing?

Looking Glass Studios' 1998 first person stealth game for Windows. In a fantasy metropolis called the City, Garrett, a master thief trained by a secret society, is drawn during a series of robberies into a plot to stop a great power from unleashing chaos on the world. The missions are mostly unscripted and maze like, with objectives to complete, and failing a key one or dying fails the level. A gem shaped meter on the HUD shows how visible you are, and guards react to sight, sound and clues like bodies or blood, with carpet and tile changing how much noise you make. Tools include a blackjack, a sword with limited combat and a bow with water, rope, moss and fire arrows. It used light and shadow as a mechanic and influenced Assassin's Creed, Hitman, Splinter Cell and Tenchu. Light, shadow and sound still decide whether a guard notices you today.
