The growth process of a human being is a fascinating thing. We pop out of a warm womb, go wah wah wah, and live months without realizing that we're a different human being than Mom.
I realize some people formed their first memory before commercial video games were around, but many of us grew alongside it. Two infants: one with diapers and a crayon-eating habit, and the other--the controller in its hand.
I don't remember exactly when, but at some point I sort of realized these things were kind of new--different from, say, stuffed animals or library books--and it somehow seemed like they were made for me. Mom and Dad didn't play them. My baby brother couldn't play them. Then one day, I realized a new game had "come out". A game that didn't exist before now did... Clearly, it was made for me.
The game was Super Mario Land... So, what's yours? Let's all date ourselves!
