I guess I find it easier to make up characters, time eras, and such. It was rare that I RPed an already made character from an anime or whatever. I was huge into drawing my characters plus making up a back story.
It's a 'slice of life' role-playing style and there isn't necessarily a plot, but depending on the partner, the story blooms itself.
If I had to choose a fandom, I guess I really enjoying RPing in the WoW universe or DND 3.5
Those count, right? Haha
