"Game Over" is a video game term, meaning the end of a game, usually ending with death. The term came before video games did. Pinball machines would have "Game Over" flashing in lights once they lost the game. When a "Game Over" happens, players might have to start from their last checkpoint, from the beginning of the level, or from the beginning of the entire game. However, starting from the beginning of a game when a "Game Over" happens only occurs in most older 1980's games, and doesn't occur in most of the newer games.
