I grew up in the 8-bit era, and was on the ball with 16-bit. I started off with Mario Bros. 1 and 3, bought an original Gameboy, played Kirby's Dreamland and Donkey Kong Land. Picked up a Sega Gen (sans Sonic) and got into the EA sports titles, as well as a little known gem called Dynamite Headdy.
I have a special place in my heart for all of those systems and games, but the N64... playing those 8 and 16 bit worlds in fully interactive 3d environments... still gives me shivers to this day. Playing Mario 64 for the first time in a Wal-mart kiosk, taking my first brave steps into the Land of Hyrule where the sun and moon rose and set, duking it out with 3 of my friends atop the block fortresses of Mario Kart... the 8 and 16 bit eras just didn't give me that sense of wonder or enjoyment.
