From GameInformer: “In 1992, Looking Glass Studios (then Blue Sky Productions) pioneered the first immersive sim with Ultima Underworld. With its non-linear, story-driven gameplay and 3D environment, the Stygian Abyss, Ultima Underworld paved the way for future generations of games like Deus Ex, Bioshock, and Thief. In 2000, Looking Glass Studios disbanded, however, its talent scattering like seeds in the wind to leave their mark on other successful franchises. But with the founding of OtherSide Entertainment in 2014, much of Looking Glasss talent has returned to continue what they started.”
