Coincidentally, I'm posting Extra Credits video the same week that it was leaked that Sony filed a patent for technology that would ban used or second hand games on its hardware. If true it is evidence of how tightly game companies are still holding onto the old ways of doing things oblivious to newer options. This Extra Credits presentation doesn't criticize such a practice, but it does talk about monetization of games and stress how the industry has moved beyond static price structures. Companies like a Sony (and by extension a Microsoft, a Nintendo and countless third party publishers) would best take notice and evolve with the times.
