2. Thief: The Dark Project
Actually, while stealth gameplay is a part of everything from Assassin’s Creed to Metal Gear Solid these days, it can be said Thief single-handedly invented the genre, while the game’s Steampunk atmosphere was second to none too.
Skulking in the shadows, you could knock guards out with Garret’s trusty blackjack, or kill opponents with a well-placed arrow to the head while sitting in a dark corner. Of course, you could also go toe to toe with foes in a swordfight, but staying undetected was always more fun. This also had an intriguing story about a long-forgotten evil coming back to the fore which was fun to follow through, in what surely is a classic game most people won’t soon forget.
