Yeah, looking back on it, it was a mistake. When I did it, I probably wasn't even a teenager yet. Didn't understand the value of things.
I had a yellow Gameboy color. I still have a Gameboy SP so I can play GB games on a well lit screen.
I think you're in the general age range of members of this forum, and more broadly Pokemon fans as a whole. I think a lot of people, as they get older, kinda clam-up about liking Pokemon, with fear of becoming a pariah. But, you're definitely in the right place to find people your age who'll admit to liking Pokemon. :)
