Valve's New Employee Handbook
You'll want to read this.
I have so much love for Valve, I don't know where to put it all anymore. Aside from consistently putting out games that are genuinely innovative and fantastic, to see that they're actually run like this just makes me want to give them a huge hug.
I know a certain game company that I may or may not have worked at, which could do with a quick perusing of this book, and perhaps a few minutes contemplation on whether their practices might need some revisiting.
