When I was 6 years old, I started to understand and like the anime series, when I was 7, I got a gameboy color with some games, one of them being Pokémon red (my parents don't know much about anything that has something to do with games, so until I was 7, I never played a game before).
My native language isn't english, and at that time I wasn't even able to understand words like save so I knew very few about the game, but that made it more mysterious for me. My nephew played pokémon too, and he was able to learn me the basics, when I started to understand everything, I began to love the games, and I'm still playing the games, even though I don't like the anime anymore.
