It's so fun to hear about everybody's first experiences with Pokémon!
I remember when Pokémon first came out in the US, and at first I actually wasn't very impressed. I wasn't one to jump on fads just because everyone else was doing it, and TV and magazine ads didn't really do much to make it look appealing to me--they were kinda just like "wow you can collect monsters!!!!!". That said, two boys in my science class who I sat behind were tremendous nerds and brought the Red/Blue Nintendo Power strategy guide to school, and I remember looking at the guide over their shoulders and being interested in the monster designs.
A little while later, I was randomly over at a neighbor kid's house, and she had a copy of Blue. I asked her if I could play it so I could see what all the fuss was about... and I was pretty much instantly hooked. My experience with video games up to that point had mostly been the Pac-Man arcade cabinet at the local car wash, freeware PC platformers my dad downloaded onto our computer (which usually only contained the first few levels and you had to purchase the full version, which we never did), and watching my cousin play Mega Man on his NES. For me video games were sort of a technological novelty more than something you could really sink your teeth into--and I was also never particularly good at them.
But Pokémon Blue changed that. It was a game that seemed to place emphasis on being immersive and inviting you to explore a charming, quirky, and comparatively deep world. And it was a game where you could succeed with grinding, knowledge, and strategy, instead of lightning reflexes and being willing to game over a million times before you figured out the perfect timing for a jump (cough Super Mario Bros.). In short, it was right up my alley, and I fell in love. I begged my parents to get me a Game Boy Color and my own copy of Blue, and the rest is history.
I'm trying to pin down a rough date of when I got interested in Pokémon. I thought I got Blue for my birthday, but Red and Blue actually came out after my birthday that year. I may have gotten them as an early Christmas present (I certainly couldn't wait until it was actually Christmas, I needed that game in my life ASAP). The first episode of the anime I saw was A Chansey Operation, which first aired in the US on March 6, 1999, and I learned about the anime a little while after I got into the games, so it was at least some time between September 1998 and March 1999. At any rate, it was great fun to be part of a craze that I felt was actually justified.
KomodoZero I was one of those hipster kids who liked (and still like) both Pokémon and Digimon. The Digimon V-pet keychains came out the year before Pokémon did, so I was actually into Digimon before I got into Pokémon. Digimon is definitely much more than "store-brand Pokémon" like my brother-in-law claims.
BlueMoonFalls I have such fond memories of playing the Stadium minigames with my sisters! I was way better at the minigames than the actual battling, haha. I recently played the Switch port of Stadium, got a few battles in, it started getting ridiculously hard, and I just went and played the minigames for a while instead because I am actually decent at those.
