It's no secret that many gamers tend to purchase used copies of video games they want, and the global consumer research and consultancy firm OTX has numbers to prove there's a significant number of second hand games moving around. To be exact, some 45 million are believed to buy both new and used copies.

As the chart on top will tell you, around 60% of 75 million consumers avail of new and used titles. While the U.S. video game market is believed to be worth US$ 17.9 billion, fresh discs only produce US$ 8.6 billion. Used games account for US$ 1.3 billion in the total U.S. software market.

Game makers don't need to worry, however, since research shows most people still purchase their games new. Only 16 million game buyers are said to be "New Game Gluttons" who buy new copies then sell after finishing the game, while the rest have enough reasons to keep their purchases.

OTX cited replayability, lovable characters, socially engaging gameplay, critical acclaim, developer loyalty, and collector’s editions as factors that compel gamers to keep games. Consequently, new IPs were found in the used market more often than installments in established franchises.
