Oh, and I remember when Mortal Kombat first came out in arcades. There was a massive controversy about all the blood and brutal finishing moves in that game. I think that was the first domino that signaled that mainstream gaming was growing up. That gamers weren't just young kids any more.
I will never forget that either. Being a young gamer myself at the time, I was totally captivated by the hype/buzz created by the advent of MK-Gore. I still remember when it hit consoles and other kids at school were not allowed to play it by parents because of media attention the 16-bit gobs of red fostered. Good times.
The very first time you walk around in Mario 64 (HOLY CRAP THIS IS THE 3D FUTURE)
That was a real good one Monsoon, kudos.
When the local rental store set up the N64 with Mario to sample-play it was awe inspiring. Most definately another "I'll never forget it moments". But more then that, I think that marked one of the greatest evolutions to witness in terms of gaming. That was a time I am very grateful to have experienced first-hand in my youth. Pure magic.
