Gorwing up, we always had a Coleco Gemini in the house. It was essentially an Atari 2600 with a different casing and a different controller: http://en.wikipedia.org/wiki/Coleco_Gemini
That being said, the NES resonated with me more. We got it in 1990 with Super Mario Bros / Duck Hunt, Tetris, Ninja Gaiden 2, and Final Fantasy. Some fun times that Christmas.
