My other main collection is movies. Bought my first DVD player in 1999 and currently have about 725 DVDs and 175 blu-rays in my movie collection. A big slice of it (probably about 150-200 discs) is anime, which I've been into since the mid-90's.
In gaming the only thing I collect other than consoles and games is Pac Man merchandise. I'll post a pic of my Pac Man collection someday when I take pics of my collection as a whole.
Outside of the gaming/movie realm, I have a small collections of art deco items, pez despensers, 80's toys and animation cels.
