There was this kind, sn of a friend of my mom. I haven't seen him in 2-3 years but last time I saw him he was somewhere between 7 and 9? and was babbling about Pokemon all the time, basically stuck to his DS playing gen 4. He harassed me to trade him some stuff when he realized how much Pokemons I had ;_;
From what I understood he was playing and discussing/planning about it all the time.
Well I'm sure there are some little kids that are big into pokemon. But there are others that just aren't as much. But back when I was around 7 to 9 years of age, pokemon was pretty much what EVERYONE was into.
I still enjoy it, and good for anyone who enjoys it as well! :3
