Some of you are making me feel so old LOL. OMG, Tomb Raider III!??! I can remember playing that on my Celeron 400MHZ in my teens.........
My earliest memory is sitting inside a cradle looking up and I was probably very young. I could see a few family members in blurry details, but mainly I just remember my uncle. He might have been play smacking me or something for all I know , that might've helped my remembering... he and a lot of the boys in my family think that sort of picking on people is funny.
Someone mentioned Super Mario which is one of my other earliest gamer memory. I was 4 and I remember the very first time I played. I was addicted from day 1. Not having a penis, this was unacceptable for a very long time so they tried to get me to play Sesame Street on NES or barbies instead. They did tell me way later though I was the one responsible for finding the free man (what we called '1-ups') before the very first hole because I kept struggling to jump over it... that felt very redeeming.
The other time I remember the most is when my cousin, of almost the same age (probably 3), we were sitting in the grass and he was trying to set a piece of grass on fire with a lighter. He couldn't get it lit, but I remember feeling like I was doing a really horrible thing by sitting there with him trying to light it. Through peer-pressure I didn't stop him though. He sucked at using a lighter and I can remember that being part of my reasoning too.
