The biggest influence on me overall is doubtlessly Warcraft III, having played a huge part in how I live my passion for games and game design in particular. It is by far the game I have poured the most hours into and a game I still play and develop for to this day, the custom map Final Fantasy Epic RPG I advertise in my sig being my main continuous creative outlet. Insane for me to think I joined the dev team for it over ten years ago at this point, and still pushing out updates.

Can't be remiss to mention Umineko no Naku Koro ni as well, which made me think like no other and kickstarted a lot of things.

More in the middle there's also Final Fantasy X with a special mention to the musical piece To Zanarkand from it. Realizing that it was my favorite game (at the time) was a major part of discovering my own identity and developing tastes different from my brother's, and learning to play To Zanarkand on the piano was something I did entirely on my own. I don't have many memories of being an actual individual in my child and teenagehood, but my appreciation and love for FFX was definitely something I didn't take on externally, it was really my own.

In terms of TV, the influence of The Simpsons on me can hardly be overstated. They're the main reason my English is as good as it is and I can probably almost recite full episodes from those first 8 seasons to this day.

I'll also mention Elfen Lied for being both my first foray into the world of anime when I was around 11 years old, and being my further gateway into it when I rewatched it just out of high school. It's probably the main reason I got deeper into the medium as a whole, in no small part due to its opening and main theme Lilium which I'll also qualify on its own.

At this point though I feel like I'd be reaching to find 3 other media that match up to these. I might edit in some more if I think of some though.
