The site includes a wealth of information, covering Japan's OCG, the prevalent TCG across many western territories, and both Japanese- and English-language Anime and Manga information, especially pertaining to the cards used therein. Video Game information (both for Japanese- and English-released games) is also contained within the Wiki. OCG and TCG cards are also searchable, where applicable, by both card and set numbers, as well as by using semantic data.
