I was about 12 or 13 when I first started watching Japan's Pokemon... It didn't hit the US until about 1-2 years after so I was that weird kid playing some weird Japanese game... Little did my friends know, haha. Then I was about 15 and I was at that age when people thought playing Pokemon was childish... Now, that I'm an adult, it's okay (or at least more accepted) to play Pokemon again, even as a young adult/adult. The key thing to remember here is that you shouldn't let others make judgments for you. Do what you want to do, you're not hurting anyone by playing Pokemon. ;3
