I had one of these, but without the sound module, which was extra. The neighbor kid had one with the sound. hehe
After pioneering the home video game industry in 1972, Magnavox disappeared for a while from the video game scene. They returned to the market in the mid-70s with a series of Magnavox Odyssey dedicated Pong-clones that were mildly successful. But, like everyone else, they saw that cartridge-based video game systems were the wave of the future.
Odyssey˛ was released in 1978 to compete with the Atari 2600. It had a lot of promise--with a built-in keyboard and more graphics and sound capabilities than the 2600, this system could have had phenomenal games. Unfortunately, there wasn't much in the way of game variety, and most of the games are real duds in every sense of the word. Only a few games--Quest for the Rings, The Great Wall Street Fortune Hunt, and Conquest of the World, for example--showed the potential of the system by combining complex video game play with board game elements to make truly engaging games.
