Nintendo Color TV-Game 6

Color TV-Game 6 is the first Color TV-Game ever released. It was released only in Japan in 1977, and featured only one game; Light Tennis, which looked and played much like Pong. The game featured 6 different modes, such as the original, as well as others with different ways to play pong such as ones with obstacles. In Japan, it sold over a million copies and was successful enough to warrant a sequel titled Color TV-Game 15. Up to two players could play this game, though there were no detachable controllers, something Nintendo would fix in future titles. Instead, there were two knobs on the console that the players could turn to move their paddle up and down. Similar to Pong, players would hit the ball back and fourth, making sure it doesn't go past their paddle. The game had bright colors as opposed to the black and white coloring of Pong. As the game's name implies, there were six game modes, each one with a minor alteration.
