I'm interested in fantasy as a whole. Games, books, movies and of course TV shows and Anime. My favorite example is Fullmetal Alchemist: Brotherhood, a mix of fantasy "science," great humor, the importance of balance, military powers and great characters set in a very early 1900s style universe. Of course My little pony is a great example too but I didn't have to specify that here I imagine.
That's my 'problem.' I make OCs and then make more OCs to expand on the other OCs a tad and that leads to one thing and another and before I know it I have about 25 OCs and then a slew of background characters.
