Censored Hentai Games
Censored games carry the pixel mosaic that Japanese law requires, and on this site that mostly means Japanese doujin RPGs and visual novels without an official uncensored release. It's not a mark of lower quality: Daitoshokan no Hitsujikai has the best player rating in the catalog, Yarimon Master and Secret Flasher Manaka are top-tier games, and DaiBanChou and Winter Memories are classics of their kind. If the mosaic bothers you, the uncensored tag page is the same ranking without them; if the game matters more than the censorship, you lose nothing here.
