Thief: Deadly Shadows is a solid entry in the franchise with some notable improvements to the formula.
Thief: The Dark Project is one of those “must play” games. Even with its few drawbacks, it’s one of the best games in the stealth genre.
Requiem is a well made story-driven mission that contains everything great about Thief gameplay.
The Dark Mod is a Thief game without actually being a Thief game.
