You may have referred to all age editions which is not censorship when done well, but there are publishers that ♥♥♥♥ up so bad it's a dumpster fire like MoeNovel did with their trainwreck of If My Heart Had Wings. Sexual scenes are already censored in the original Japanese game, they have laws or rules that say genitals must be covered by mosaic, which is interesting considering they are so big on some seriously sick stuff.
