I mean, sure, but the discussion isn’t only about PCs, the question in the screenshot was about the series X. You can find pre-owned discs for consoles sold on gamestop, for example.

I honestly don’t get the obsession

Selling the game after you’re done is the biggest one I heard. If you’re playing a single player game that you don’t expect to want to do another run of, you can recoup some of the money. Similarly, some people prefer to buy somebody’s copy for 80% of the price they would pay on the digital version.

I’m looking forward to FFXVI myself, loved the demo, it’s shaping up to be a pretty good release.
