Microtransactions - Horse Armor Pack in Oblivion

The Horse Armor Pack for The Elder Scrolls IV: Oblivion was introduced as a downloadable content (DLC) option, primarily serving as a cosmetic enhancement for players' in-game horses. This pack allowed players to equip their horses with armor, which, while not providing significant gameplay advantages, offered a way for players to personalize their gaming experience. The introduction of this DLC marked a pivotal moment in the gaming industry, as it was one of the first instances where players could purchase additional content for a game post-launch. The popularity of the Horse Armor Pack contributed to the growing acceptance of microtransactions in the gaming community, influencing future game developers to explore similar monetization strategies. By 2009, the Horse Armor Pack had become one of the best-selling items for Oblivion, demonstrating a successful model for DLC that many games would adopt in the years to follow.
