A sealed cartridge with no “DLC Update” sticker has a different aura than one marked “latest patch applied.” Collectors of physical retro will prize untouched artifacts; completionists of software will chase the most recent update. Both impulses coexist. The treatise argues for transparency: DLC should be documented, versioned, and reversible where feasible, so that both archeologists and completionists can satisfy their appetites.
