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.
