I remember the day my dad brought the Atari 2600 home. It wasn't even my birthday or Christmas or anything. My dad (who was always big on technology, was the first in the neighborhood to have a VCR and DVD players too) was late coming home from work. I hear the garage door shut then see him coming through the backdoor with a box on his shoulder. It took me a few seconds to realize what it was. Awesome kid moment.
I've never been REAL good at most games, so anytime I beat one of the "big" games (Zelda, Metroid, Contra, Dragon Warrior, etc.). Ninja Gaiden in particular. Man, what a pain that final boss was.
