I'd love to see more video game-related things! I'm sure there's tons of anime stuff that I like that hasn't been represented much here yet, either, but I noticed in particular that there is a disturbing lack of Gintama. It has some of my favorite songs ever, so I'd love to be able to collect them one day. I'd also love to see more seiyuu decks, because ugh, voices, voices are one of my biggest weaknesses...!
