Age of Empires II was released in 1999 by Ensemble Studios and became one of the most enduring real time strategy games, helped by short, characterful unit voice clips that players heard hundreds of times. Small exclamations like this Oooh were easy to isolate, share and recognise out of context, especially alongside the game's other famous monk and villager sounds. As soundboards, streams and short edits grew, the clip survived as a nostalgic shorthand for amazement, instantly signalling a classic PC game reference without needing any footage or explanation.
