Warren Spector, the designer behind Deus Ex, Thief, and System Shock and widely regarded as the founding father of the immersive sim genre, has announced his retirement from game development. He posted his decision on LinkedIn on August 18, noting that the industry has changed and that making games "just isn't as much fun" anymore.

The details:

Spector is 70 and cited age and health as factors, alongside a feeling that he had accomplished what he set out to do across a career spanning 17 full games and nine expansion packs. "I've done what I set out to do," he wrote.
In his statement he said: "The game business has changed and it's just not as much fun for me anymore. Plus there's a new generation of developers coming up who deserve their time in the sun."
He acknowledged there are still three games he would like to make: one very big, one very small, and one he does not know how to make yet. He did not elaborate further.
The retirement follows a difficult final chapter at OtherSide Entertainment, which he co-founded. System Shock 3 stalled after IP rights complications, Thick as Thieves launched in a troubled state and lost support two months later, and Argos: Riders on the Storm was cancelled after OtherSide made layoffs in June 2026.
He closed his statement with a message to younger developers: "Your job is to make people forget people like me ever existed."
