I like role play games such as Dungeons and Dragons (3.5 in particular!). My favorite kinds of cosplays are video games, comics, and sci-fi. My favorite would have to be my Leeloo costume which I had made for halloween a few years ago! I love going to cons and hanging out with my friends doing nerdy things like watching a good ol' sci-fi show, playing our table tops, or just hanging out discusing nerdy things.
I'm also very involved in my theater community where I live. Theater is a big part of my life, which probably helps my love for cosplay.
