My parents got into gaming at about 18-20. They bought a ZX Spectrum, and they played PC adventure games like Monkey Island through to about 1995. Then the genre died and they stopped any kind of gaming. The only games they have played recently are the Telltale Monkey Island, and they were interested in Simcity 5 until I told them it was all online and socially integrated. I would say the game industry basically failed to have what they want and that's the only reason they stopped.
Myself: Mario Kart 64 followed by Super Mario Bros. (GBC), age 6-7.
