According to The head of gamestop they want to possibly take a shot at selling used digital games. Meaning you can trade in games you have downloaded.
"We're interested," Raines tells Gamespot. "It's not a meaningful business yet. Right now we're not seeing that as a huge market, but I think we're on the leading edge."
So according to the article they've been checking out similar tech in Europe as well. Im curious as to how the hell people could trust a digital game trade in. I don't fully understand how the hell they could implement this, unless someone would like to enlighten me.
