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.
hehe....to be honest I got my first Yellow around the age of 11...^^;
Also I got it one day walking to school, it was on the ground =DDDDD such luck! haha XD
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.
