GI:Nineteen ninety-eight saw the release of two landmarks in the stealth genre. The most notable was Metal Gear Solid, a game that is considered one of the best stealth games in history. However, there was another title that came out shortly after Metal Gear that played an important role in defining the stealth genre. This was Thief: The Dark Project by Looking Glass Studios. Unlike other games that have heavy stealth components, such as Deus Ex, Tenchu, and even Assassin’s Creed, stealth is the only way to progress through Thief: The Dark Project and its two sequels, Thief II: The Metal Age, and Thief: Deadly Shadows. With Square Enix and Eidos Montreal working on a new game in the series and other current games like Dishonored that seem to draw inspiration from the project, we thought it was time for a look back at the landmark series.
