Used to play on my stepdad's Commodore 64 but no idea what any of the games were.
Later, the Zork series, Lightspeed and Star Trek: 25th Anniversary on our old 286. Mavis Beacon Teaches Typing when I was forced to. Where in the World is Carmen San Diego, but the "Where in Time" one was better. Honestly don't remember which of those came first. Probably Zork. I probably spent hundreds of hours playing Lightspeed and its follow-up, Hyperspeed (pick it up on Steam or GOG).
First NES game was Super Mario at my neighbors' house, starting around Christmas of 1985. That little redneck only wanted to play Duck Hunt, though.
