At the very loving least, everyone needs to pick up San Andreas for $3.74, that's a loving deal. Probably the best one I've ever seen on Steam, if you take the time I spent on that game and divide it across price, that's 11 cents an hour, or roughly 220 times more entertainment time per price than a song off of iTunes.
ergo, if a 3 minute song was lengthened to 42 hours long, it would cost $831. You're getting around 42 hours of entertainment for $3.74.
