Supernatural/Ghosts: My Oma/Granny put on a ton of ghost hunting shows in the background when I was 5, 6 or 7. That lead into other related interests.

TLoZ franchise: Got introduced to Zelda: The Wind Waker at 8 yrs old. It increased in intensity once I saw a trailer for Majora's Mask 3D, and I learned more about the other games.

Splatoon: Saw a trailer for it in 2014, immediately latched on to it.

Bonus (Coroika): I once bought the first Splatoon Manga Vol. without realizing how big of deal the manga series would be to me years later, but I really did like Rider, Army and Aloha from it. Team Blue was just so out of pocket at times though, I laughed way too much back then TuT
