Answer: The legend of Zelda
The first arcade games were meant to be played in one sitting, often as a kind of test address in which the player was trying to go as far as possible and / or acquire the most points. When video game consoles arrived, they imitated the same type of gaming experience as in an arcade: you played as long as you could to get the highest score possible.
The introduction of Nintendo's The Legend of Zelda in 1987 (North America and Europe) marked a dramatic shift in console gaming. The Legend of Zelda gold cartridge contained an internal battery that powered a small RAM chip that recorded the player's progress. For the first time, console players could save the game at any time and come back later. The games were no longer limited to a racing style going to the end. As a result, the size of the game world and the complexity of the game could be greatly expanded, as designers knew that players would be able to complete the game in multiple sessions as they pleased.
The extensive game and the rich environment have been a hit with the players. The Legend of Zelda was the first Nintendo game to surpass one million sales, ending up selling 6.5 million copies. It is one of the most popular video games in history.
