[Nintendo 64 U.S. Unveiling @ E3 '96 in Los Angeles, California]
At the second ever E3 conference, there were several revolutionary developments showcased. Starting with what is arguably the most prominent of the conference, Nintendo's 64-bit and first 3D console, the N64, made its premier appearance at the '96 E3. The game shown alongside it was the widely-known Super Mario 64. The game's innovative interactive 3D environment, the N64's analog control stick, and the ability to change camera angles in-game, surely blew the minds of many gamers of the day.
For myself and gamers of my generation, the N64 was the first console we owned (I still own mine), and became the console of our childhoods. The N64 went on to see games like Super Smash Bros, Star Fox 64, Kirby 64: the Crystal Shards, Pokemon Snap, and countless other titles that defined a new generation of gaming -- and that's not even mentioning all of the classic Rare games on the console as well.
Besides Nintendo, this 1996 conference saw the reveal of Square's (Now Square Enix) Final Fantasy VII, which won countless gaming awards in 1997, and has gone on to be considered one of the greatest games ever made.
Other games featured at the second conference included Naughty Dog's Crash Bandicoot, Blizzard's StarCraft, Tomb Raider, and Capcom's Resident Evil. Pretty big year.
