23/8
First games I played were various Atari 2600 games whenever we visited my cousins who had one. I also played games on this odd Texas Instruments computer thing. It was a keyboard with a cartridge slot that you could connect to a TV. Eventually we visited one of my mother's friends in Canada, whose kid had a Nintendo, so I asked for one for my birthday in maybe '90 or '91. I was so engrossed in it at one point, that when we planned on visiting another of her Canadian friends, I asked if I could bring it along. The other person, hearing me over the phone, suggested my mother buy one and bring it with her, and she could pay her back for it in Canadian money rather than us having to go exchange funds. I guess it was because electronics cost less here or something?
Edit: Whoops, misread the question. I'm 23, and have been playing games since I was 8, so that's 15 years.
