"Thief II" received positive reviews from critics, and its initial sales were stronger than those of its predecessor. However, the game's royalties were gained slowly, which made Looking Glass's financial troubles worse. As a result, the company closed in May 2000, with plans for "Thief III" cancelled. The third game in the series, entitled "", was developed by Ion Storm and published by Eidos in 2004. "Thief 2X: Shadows of the Metal Age", a widely praised expansion mod for "Thief II", was released in 2005. In 2014, Square Enix published a reboot of the series, developed by Eidos Montréal.
