This post is not at all interesting unless you play video games!
As I was playing this game I was not surprised that my son would like it and recommend it so strongly - - besides the ability to rewind time and discover what that means, very nice music and the what the heck is going on factor - - it has a philosophical feel. DH heard an NPR report about the game, calling it a "masterpiece" and as having a "meditative feel" and here is the link to the audio clip, from All Things Considered.
The text on the page is not a transcript of the clip, so if you are interested in what's being said about the success of this game, click on the audio.
Note to my brother: I think you'd like this game!
