The strange thing about video games is that the prices have never really gone up. It flies in the face of basic economics, but the duality of games costing much, much more to make and the amount of people who buy games skyrocketing, the magic price of $50 a game has stayed pretty constant. I remember some $60-$70 N64 games. People today would freak out if a modern generation game cost that.
It can't last forever, though. Who knows, maybe this will be the generation for a lasting price increase?
