31.
First console, Atari 2600. Used to love getting dropped at the arcade while my mom did the grocery shopping. [Back when arcades had more than racing, fighting, or gun games. And everything cost a quarter.] I was so excited that day I put my dollar in the change machine, and I got the Red Token, which you could turn in for 5 bucks in tokens. I smiled all day.
Atari 2600-> Atari 7800 [my next door neighbour had a 5200. Got Defender for a birthday [from my grandmother!] and stayed up all night playing. First all nighter : )]. NES for a while, then didn't game much [at least on new consoles, and other interests--work, biking, comics, girls, extracurricular activities] till high school [or was it college?!?], when I got a Genesis thanks to a friend and Shining Force. Then the Sega CD and the monstrosity known as the 32x, then the PS1 thanks to Vandal Hearts; sometime after that a brief fling with the Saturn, then last Christmas the PS2.
Now married, a 19 month old son, and real life intrudes on gaming as much as I'd like to. But I still try to play at least an average of 1-2 hours a night, after babybutt goes to bed and we've done all the household things.
