NES at my newphew's place when I was 12 I think. We played Mario and Duck Hunt on it. It didn't impress me much at the time since I was into PC already, King's Quest, Space Quest, Police Quest, Rogue etc. I wasn't interested in platformers at the time after MSX, got back into them with Prince of Persia, Rick Dangerous and Duke Nukem later.
My Nintendo 'journey' started with N64, Waverace, Mario 3D, OoT. Original Mario I first finished on Gameboy color on a 8 hour flight. Done long before the flight ended, then played more Tetris. (At my nephew's place we didn't get much past the second world lol)
