Thief: The Dark Project, created in 1998, was a standout title in a year punctuated by other classic video games including Half Life, Starcraft and Unreal. It is credited as the inspiration for strong stealth mechanics in first person titles such as Deus Ex, and the Dark Engine was the basis for another classic: System Shock 2. Looking Glass Studio's legacy therefore is not to be trifled with, as legions of fans will attest.
