Warcraft II: Tides of Darkness, released by Blizzard Entertainment in 1995, gave its human worker units, the peasants, a set of short spoken responses for when players selected and ordered them. The brief Okay became one of the most familiar of those acknowledgements, partly because players heard it constantly while gathering wood and gold and building structures. As strategy game clips and retro gaming memes spread online, the line survived as a compact agreement sound, still used today because it is instantly understood even without any knowledge of the original game.
