Overview
Every problem, multiple solutions. The immersive sim emerged from Looking Glass Technologies’ commitment to player agency—games where systemic rules create emergence rather than scripted sequences. Ultima Underworld established the template; System Shock refined it; Deus Ex codified it. The genre never achieved mass market dominance, but its design philosophy influenced everything from BioShock to Breath of the Wild.
