13 or 14 i think. My friend forced me to play emulated Pokemon Blue on his pc although i heavily resisted, well it didnt take too long that i bought Pokemon game of my own, which happened to be Pokemon Yellow.
I was 12 years old and one of my friends gave me a copy of Pokemon Red Version because he found out that I loved Pokemon but I had never played the games. I started late. I bought myself a GBA. (Ruby and Sapphire were not out yet by a long shot.) I played all the older games starting with Red and ending with Crystal.
Whats funny is that even in elementary school I'd pretend I was a Pokemon or a trainer with my friends on the playground. I liked Eevee even then but I didn't use her til gen IV because I wanted a whole team of them.
I am guilty of being an insufferable smart ass! Too many people I know would be perfectly content to burn me for a witch.
