My comic Doragon Konpaku has multiple inspirations, but arguably the genesis of it was Asura's Wrath's story and music, largely music. A few characters of the comic take subtle cues from ones in the game, and it was the initial basis of the story's origin. I also have inspirations from Naruto and Bleach, to very limited degrees in cases.
I get inspired a lot by music from across countless video game series, cultures, etc, and really never know when new ideas will come my way.
Example of the music I use when working on certain parts of the story:
