I remember getting a blue Game Boy Color with Pokemon Blue for Christmas in I want to say 1998 (so I was about 6 years old). My older brother got Pokemon Red at the same time, and his name was subsequently what I called my rival "Gary" character. Played the shit out of it but, being a little kid, sucked at it -- don't remember ever actually
beating it. Traded with and battled against my brother a tiny bit when we managed to get one of those Game Boy connection cords.
Had
a Pokemon handbook that was really useful in laying out what each abilities each pokemon could learn, what they were good against, how they evolved, etc. Got a lot of use out of it and subsequently wore out the spine so that I had to tie a rubberband around it.
Collected the cards and played against my older brother at times, but I mostly liked looking at them all displayed in numerical order in a binder I had. Definitely got ripped off in a few trades with my brother and his friends and lost a few good cards to friends that moved away over the years. Remember going a couple times to a local Toys'R'Us where my brother and I would play against and trade with other kids during trading card game nights.
Watched the anime quite a bit when it was on TV, and we even had a few episodes on VHS. Was always really interested in the snacks that Brock made.
My older brother ended up playing Yellow, Gold, and Crystal, but I only ever stuck with Blue (and Red at times when my brother allowed it so that I could collect some of the Pokemon not in Blue). So I never really got into anything other than Generation I. Kinda crazy that there are like 10 generations now. Sorta fizzled out on it around middle school. There was, however, a resurgence in high school (probably around 2010) of everyone on my track team starting to play it again, which was sorta funny, but then it disappeared over summer break.
Overall, really nostalgic for me.
