The first video game I ever played was I think Paper Boy for the Atari. Game sucked balls. As for the first game I ever owned, Super Mario Bros 3, I was probably like 3 or 4 and I vaguely remember going with my parents to buy it.
Never got past the second zone cause I was an inept child, but I recently played at a friend's and we couldn't get past the 7th zone. Game is actually pretty damn challenging (or maybe my video game skills have deteriorated in an age of regenerating health FPSes and auto-saves).
But yeah, awesome game.
