Age of Empires II, the real-time strategy game first released in 1999, lets players build stables to train cavalry units, and its short building and unit sounds became familiar to a generation of PC gamers. Short clips from the game later circulated on soundboards and in gameplay videos, where tiny effects like this whinny were reused out of context for jokes and edits. Its appeal endures because the sound is instantly recognisable to strategy fans while remaining short enough to slot into almost any video without interrupting the action.
