You're not actually all that religious, but Oh,
It's like all Hell has broken loose, maybe
All you know is that something is really,

IWATC is a narrative-focused urban fantasy RPG where it doesn't matter how strong your werewolf is, or how fast his vampire is, or how beautiful her fae is…what matters is how these characters feel, what drives them to do things, not how inherently capable they are of accomplishing them. What keeps the viewers of Buffy or Teen Wolf or any other young-adult urban fantasy show coming back every episode? Is it the Monster of the Week? No, it's the angst and drama of the young adult characters' lives, how they face the paranormal shinola they're wrapped up in. Come play a character that could star on such a show, and see how their angst and emotions drive their story.
Player characters in IWATC each have a Trope, summing up who they are or what purpose they serve in the story. If you get a character sheet that says "Ditzy Cheerleader" or "Computer Nerd", you already know how to play that character. The rest is figuring out what it means when your Trope is a Werewolf, or a Ghost, or a Hunter, or whatever.
