Oh god.... Take a walk down memory lane - the three I remember playing first were...

Pong on my uncles Atari:

Donkey Kong on my baby sitters arcade version she had in her game room:

And The Legend Zelda on my grandmothers NES, lol (The woman actually mapped out the entire game on graph paper - god love her for that obsessive gaming personality even at her age back then.)
