"Buying and selling used video games has become a fact of life for many consumers -- but if game publishers get their way, it's about to become a lot more difficult.
One 2009 estimate puts the size of the used game business at about $2 billion, representing about one-third of all annual game sales. That's a big deal, especially for market leader Gamestop, which is thought to get over 40% of its profits from reselling traded-in games. Major retail chains like Best Buy, Walmart, and Amazon have all dipped their toe in this lucrative market over the past year."
