Well my first console was a Sega MegaDrive (the II edition one) which I had bought because one of my friends had one and Micro Machines is awesome.
In about 1998 I think, I bought an N64 for £75 in Sainsbury's with F1 World Grand Prix II in the box.... I wouldn't say I was a Nintendo fan then though, still just a light gamer buying a few games, not really properly aknowledging that i had bought a console from a different company, my friend (different one to the one who had the MegaDrive) had The Legend of Zelda: Ocarina of Time for his N64, I was sceptical at first about the concept behind the game, but we took it in turns playing and apart from sleep and such pretty much spent an entire 3 days playing the game from start to finish.
That was when I became a Nintendo fan.
Having said that, OoT is certainly my least favourite Zelda... it has aged.
