Except this argument doesn't work here, at least based on the model proposed in the article.
The article is saying that this can still be the case - in this model, you'd trade in your license for credit towards a new game.
It would actually be pretty brilliant. The biggest loser would be GameStop.
So you can't buy a used game for 90% of the new price, and sell it for 120% of the used price, but maybe you can sell it for 50% of the new price.
I am very, very OK with this model, but who knows how it will actually work.
