I'm 18 going on 19 relatively soon.
I've played Pokemon since 1999, with Yellow being my first Pokemon game.
I didn't really get into it until the 2nd generation came along when every kid in my neighborhood owned the game. It died out in my area around the 3rd generation era, but I still kept playing, and to this day I still play it. I'm mostly into the competitive aspect of it nowadays, since it involves so much predicting, knowledge, and calculating.
