My true and very first game was on the Commodore 64. It was a dinosaur educational game. You could play as three different dinos. A Setgo, T-Rex, or Bronto, and you would eat leaves if you were the herbavores fight off the T-Rex. If you were the T-Rex, I was usually always the T-Rex, then you would just come out and attack the herbavores. After you win, you would get a print out of information(on the old dot-matrix printer) on the dinosaur you used. I wish I knew the name of that game.
cgspartan - Stars Wars: A New Hope was a pain in the butt. I never could get past the second level.
My first real 'gaming' system was the NES, or GameBoy (Black/White Tetris, oh yeah) I can't really remember which came first. I think I was seven when we got the NES.
Ahh, good times.
