My brother got Blue, I chose red. I was gullible back then, so on the day it came out, he made me think they didn't have any more of the Red Version, until I got home and figured out he already bought one for me.
God I can't be bothered to do the math but I had the game along with a new Gamboy Colour so I must have been around 7. Brings back memories though of me and my friend trading Machokes and Kadabras so we could get Machamps and Alakazam to complete the Pokedex.
Pretty sure I was out and about skiving classes in my second year of college when I met up with my brother in town and he showed me Yellow in the store that had imported games... So I was about 17 I think.
