Twelve original video games, alongside several ports and other spin-offs, were released by Looking Glass Studios, an American video game developer, in its ten years of activity from 1990 to 2000. The first Looking Glass Studios video game was Ultima Underworld: The Stygian Abyss, which was released in 1992 and received widespread critical acclaim and sold nearly 500,000 units. The studio proceeded to develop titles in multiple genres, including role-playing, sports, flight-simulation, and stealth video games. These were primarily published by Origin Systems, Electronic Arts and Eidos Interactive, with three games self-published by Looking Glass Studios. Their products were praised for innovations in video game technology and design. Several of their successes, such as Flight Unlimited and Thief: The Dark Project, sold more than half a million copies each. Its final project, Jane's Attack Squadron, was completed by Mad Doc Software and released by Xicat Interactive in 2002. (Full list...)
