It didn't come out in Britain 'til 1999, when I was ten. Being a hardcore GB enthusiast, I had heard of the game (and played my friends import copy), rushed out on release and bought Blue (for me) and Red (for my brother). Eight years on and my Blue Gamepak (and box) is still in near mint condition.
Of course, whilst the cartridge is still in great shape, I can't say the same about the data on it. Missingno. scuffed that up years ago. My hall of Fame has never been the same since.
