What was the first console video game that allowed the game to be saved?

During the 1970s, the first generation of home consoles emerged, including the popular game Pong. From 1978 to 1982 video arcades became popular in malls around the world and affordable home consoles, such as the Atari 2600 and Intellivision, enabled people to play games on their home TVs.

The introduction of Nintendo's "The Legend of Zelda" in 1987 was a radical shift in console gaming. The "Legend of Zelda" cartridge featured an internal battery that powered a small RAM (Random Access Memory) chip which stored player progress. For the first time console gamers could save the game at any point and return to it later.

As the technology grew so did the gaming business. Next came 8-bit units in 1983, then 16-bit models emerged in 1987, then on to 32 and 64-bit units in 1993.

Now 3D is beginning to be a force and Artificial Intelligence (AI) is just around the corner.
