I've been deep in learning how to rewire sections of my house, trying to understand the logic behind my older (1950s-era) electrical system. In the process, I came across a free game on Steam called Wired developed by the University of Cambridge's Engineering Department. It's a puzzle game that gradually introduces core concepts in circuitry and logical flow. It doesn't replace proper training, but it is an engaging supplement compared to reading electrical code books.

But anyways, I though I would ask about games that don't just entertain but also teach. Not strictly edutainment in the shallow sense, but games that impart understanding, intuition, or practical knowledge through their mechanics.

What are some games you've played that taught you something substantial? I'm thinking anything from real world skills, conceptual insights, functional knowledge, or anything that stuck with you after playing.
