StarCraft is Blizzard Entertainment's 1998 real-time strategy game, and its interface sounds became part of the language of PC gaming. Every order given to Terran, Zerg and Protoss units is answered by short clicks and beeps, including this quiet confirmation tone. Because matches were streamed, recorded and parodied for decades, those UI noises travelled far beyond the game into forums, videos and soundboards. Players still recognise the hit immediately, and creators borrow that recognition to make any on-screen selection feel official, tactical and complete.
