I was just thinking about what got me into different things like anime/ games/ comics etc and thought it would be fun to see what brought others into the fold. For me it was
Anime: Princess Mononoke, saw it when I was 10? And it completely floored me with the art style, story, and lore. Still my favorite anime movie to this day.
Video games: Sega Genesis/ sonic the hedgehog and altered beast with my older brother were great times when I was little and got me into gaming.
Comics: Spider-Man and X-men on fox kids in the 90s and Spawn in 97. My first official comic/ graphic novel was Wolverine: Origin
Anime: Digimon Adventure I first got into it when it was airing on Fox Kids, while I was in elementary school. I absolutely fell in love with it. Then, for nostalgia's sake, I streamed it during high school summer vacation. I was surprised by how much I still liked it, and wanted more. I got into Fullmetal Alchemist and that sparked more.
Comics: Fleischers' Studios' Superman My mom bought me some of these Superman shorts on VHS when I was really young. I loved them. They were my first exposure to superheroes. Then later on, I got into Batman: TAS and the Spider-man and X-men shows on Fox Kids.
Sci-Fi Star Trek The Next Generation I've been into Star Trek for as long as I can remember. Star Trek TNG, Deep Space Nine, and Voyager re-runs were on constantly in the 90s. I didn't get into the Original Series until I was into high school. Star Trek became my jumping point into Star Wars, Orson Scott Card, Arthur Clarke, Robert Heinlein, Stargate, etc.
Fantasy Harry Potter and Narnia I was exposed to both of these in a public school. (Can you imagine C.S. Lewis taught in a public school today?) While I had enjoyed fairy tales and Disney adaptations thereof before these, Harry Potter and Narnia really got me to appreciate Fantasy as a long-form literary genre.
Video Games Sopwith My family didn't have video game systems,, and my parents were generally opposed to me playing them when I was young. We did, however,, have computers. For some reason, computer games were considered to be different. My earliest game memories are playing Sopwith on an old DOS system that we had in the basement. Then, when we got a more modern computer, I played Harry Potter games, Lego games, Runescape, and online flash games.
Horror Dracula I don't remember exactly when I got into old-school Universal Monsters, but Dracula and vampires were a very early interest for me. I had a comic adaptation of the original Dracula novel that I absolutely loved.
Music Danse Macabre by Saint-Saens/Greatest Hits 74-78 by Steve Miller Band I was exposed to Danse Macabre in elementary school music class, and it was the first piece of music that I remember really getting into. Then, in middle school, I really got into Steve Miller Band when my dad was playing it on a road trip. I sparked a rabbit hole into Lynyrd Skynyrd, The Who, Ozzy Osbourne, AC/DC, and a life-long love of rock and metal.
