For my 7th birthday, my birthday cake was the "?" block. I just saw this picture a year ago and felt like someone should have beaten my ass for such a bad idea.
In 4th grade, I invented my own video game that I acted out in real life. I got some kid to be the Luigi to my Mario. It was mostly just jumping around and pretending each part of the school yard was an area. Fortunately, the recess was packed with about 500 kids so nobody noticed. I felt like a total tool so one day I stopped. The kid asked me to play and I pretended like I didn't know who he was. I don't remember his name.
In 6th grade, I wanted to take my video game idea and turn it into reality. There were two girls (both turned out to be hot) that had crushes on me who got scared away. I was determined to make a Mario 64 like game with QBASIC. I shit you not. I found a kid who said he knew about it but in reality, he didn't know how to do anything. I got three other guys with me to program. We spent most of the time watching TV and playing. One of my dogs started humping the legs of the supposed programmer and wouldn't stop. I figured it was acceptable justice for being a fraud.
I bought all kinds of Strategy Guides for the games. One time, I lost one and was almost obsessed with retrieving it. I almost got into a fistfight with a kid for not returning my Mario Kart 64 guide in pristine condition. Only thing that held me back was my Mom saying she'd buy me a new one. She didn't and I hated her for the following week.
I've drawn and designed almost a dozen games on notebooks. Before throwing them away when heading to college, I looked at them and thought they were crap. It was barely anything more than rehashes of games like Super Mario 64 and Goldeneye. So nothing real of note.
What basically stopped this extreme nerdery was that I took up weight lifting and joined the football team. Since I didn't have time to get into gaming obsessively, I had to cut down on strategy guide hording and obsessive gaming habits in general. I still spent all my free time gaming when I wasn't at practice, parties, or work. Giving up the hardcore gaming didn't happen until early this year, almost 21.
