I am just happy to be able to say I was able to go to E3 once. Way back in 1997 when it was hosted in Atlanta. I was only 14 years old. The company my dad worked for started to make PC games and due to the games having a lot of full motion video and he was a video editor, he was now making PC games. They all went down there and my dad was able to get passes for me to go to the show. As a 14 year old it was amazing. I still have a bag in my mom's attic full of all of the swag I got.
I was huge Nintendo fanboy at the time, and spent a ton of time in the Nintendo booth. I got to play so many games.
One of my favorite memories was playing through the The Lost World: Jurassic Park arcade game on the show floor. I was (and still am) a huge JP fan, and being able to play through the entire game, with my dad, without spending any money was a treat LOL. No one was in line to play, so we just played through the entire game. It was awesome.
Another was playing Star Fox 64 multiplayer in this huge theater/screen. Everyone sat in these cockpits when playing that angled up to your portion of the screen. They had the rumble pack wired into the seat, so it would rumble as well. When you got eliminated, the seat would lower back down. If you won, you got a free N64 controller where the top shell was gold and the bottom shell was black. I got second place and was mad I did not get the controller, LOL.
