Same here, kid thing for me, at the time, but I know plenty of people who watch it still at my age..
I had a gold Raichu when it was rare at it's time lol.. but I think my brother took it and just threw it away. I had it stashed where I thought no one would find it, and of course I went back to get it, and nope wasn't there.
I was mad, and ever since then I stopped playing the game, and stopped watching it all together. By then I think I was to old to watch it, and just couldn't get into it anymore.
