Exactly. This will create an incentive to turn even more games into "games as a service", so that you don't return it, or free to play, so that there is nothing to return. Modern games are already optimizing for "long term engagement" at every turn, with a $60 box product like Modern Warfare packed with Battle Pass and seasonal grinds. Gamers want less of this and more God of War, a game where most it's value is consumed in 1 or 2 play-throughs. That'd be incredibly unfair to developers of story driven games if people can burn through the campaign in Uncharted and then resell it for 80+% of the price (since digital used goods have no wear and tear and no risk of defect due to age, I'd presume the resale prices will be near-retail)
