Very nice idea! Might inspire some people to represent the old fandoms once more in the game. I like this ^^
I have quite a few that I can remember and have seen over the years:
Ginga series, Wolf's Rain, Balto, Hetalia (omg Ascension Island was the motherload of that xD),Attack On Titan, Markiplier, Jacksepticeye, Pewdiepie, Friday the 13th, Nightmare on Elm Street, Star Wars, Disney, World of Warcraft, Warriors, Pokemon, My Little Pony, Blackblood Alliance, vocaloids, Invader Zim, Marvel, Hunger Games
There may be more that I think of so I will post those later on if I think of any.
