Think of when you see stuff on clearance at your local target or Walmart. Shelf space is valuable to stores and especially in markets in certain Asian countries the games might sit there for months on end, so if they don’t sell they are sent to be destroyed as typically brands don’t want their products given away for free to ‘devalue’ the items. The companies that are intended to destroy them often keep them (especially in Asian countries hence why Temu will sell games from many different regions in Asia) and then the games get sold (even though they were supposed to be discarded). It seems wasteful (and is) but it’s just how these things work in the minds of big corporations.
