One of my favorite things to do while watching blurays, is to listen to the commentary, and hear all the interesting facts that went into making a film. It can often be funny, very insightful, informative etc...
This has carried over into a few games, that offer a developer commentary mode where you get to learn interesting details about the development of the game or weird bugs that happened along the way. I was recently reminded of this while playing through Chronicles of Riddick again and struck by how fascinating it all is.
This thread was created just to put down a few games that I have played with it enabled, and to find games that maybe other people people didn't know had it enabled.
