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: The DIC dub of Sailor Moon.
Yes, the heavily-censored one. Yes, the one with the "cousins."
But if not for that entry point, I would never have discovered a truly wonderful art form that, over 25 years later, I'm still a huge fan of.
Video games: The NES Action Set, in 1988. One of the last released with the gray Zapper, in fact.
