StarCraft is Blizzard Entertainment's real-time strategy game, first released in 1998, in which players harvest minerals and vespene gas to build bases and armies. When a player tries to train a unit or construct a building without enough gas, the game plays this short announcer warning. The line became familiar to millions of players through long sessions of multiplayer matches, and later spread through gameplay clips, streams and memes where it signals any shortage, from in-game resources to everyday budgets.
