A couple years ago, I was looking around the internet to see how many compies of certain games were sold over the years. I looked up Super Mario, Pokemon, Grand Theft Auto and Call of Duty. VGChartz came up and it was cool to see that they had up-to-date stats on how many games have been sold for months. I keep coming back every week to see what the top games are and to see if some of my predictions are right.
