Thief in Dishonored
Dishonored has really been influenced by the PC classic Thief: The Dark Project. To show the Devs appreciation of the game, the studio included a little easter egg. You can find it in Mission 7: "Flooded District" at Daud's Base. Once there, look for the two guards in training. The speech you'll hear is pretty much identical to the tutorial mission from Thief. the Dark Project.
