Sometimes it’s about learning from what doesn’t work.

More stuff from Introversion’s canceled Subversion project: this time procedurally generating building interiors.

Generating interesting and realistic modern building interiors is difficult, as many modern-setting roguelike designers have discovered to their dismay. It’s an open problem, and very few games have managed to make personal-scale procedural generation work in a modern setting. Maybe you have an idea for making it work? Or know of a game that does get it right? (There’s some unreleased projects I have great hopes for.)

In the case of Subversion, they discovered that it was more interesting to design the buildings and defend against the heists rather than executing them, so they switched to making Prison Architect. Which, alas, has less procedural generation, though it does have agent-based AI.
