Microsoft suggests the possibility of reselling the digital games for Store credit
The idea certainly looks interesting, but it is not the way it is presented, because it assumes a very small gain from users. The exact question in the poll is: " If the digital store on your console to offer its users the ability to resell their games for a 10% of their cost in store credit, would you be interested in an offer like that? "
The problem here is evidently in the percentage of pricing games, the 10%: This means that a purchased game to 60 Euro for only 6 Euro, an assessment would be resalable definitely inconvenient even for older games a few years. If the percentage was raised to 30% or more, could start to get interesting.
Obviously, for now there is nothing concrete behind this poll, as well as the fact that MS is probing the ground for the idea: we know that the company is actively looking for better solutions for sharing and resale of digital games, so hopefully we'll have some concrete news as soon as possible.
