Would you "sell back" your digital Xbox games to Microsoft for 10 percent the purchase price in Xbox Store credit? That's the question Microsoft is apparently putting to customers as part of a new survey that popped up on Reddit.
Assuming a $60 purchase price, 10 percent would be $6. As pointed out in this NeoGAF thread, that may not seem like much. But currently, a digital game has no real residual value as a physical one does.
