I don't remember which game, but my parents had an intellivision that I barely remember messing with. They also had an old Pong machine. Then we had an apple 2+ computer that I used to play Hunt The Wumpus on. When I finally got an NES, SMB was the first game I owned and played to obsession.
Oh yeah, and we used to play Number Munchers and the Oregon Trail in school. Also this other game where you had to use tools and pick plots of land to find fossils and stuff.
