Well, I’ve wondered if Peach Princess have been thinking about offering some of their games to the fans of the genre in Japan? They COULD sell games like Maid’s story and Critical Point LCE (both of them still has the mosaics) and eventually some other games where the mosaics couldn’t be removed for some reasons, like Dokusen…
They might not sell all that many copies there, but I’m sure of that there would be fans who’d buy them anyway just because thet they’re fans of the genre - and they might find it interesting to play through the games in english (for much the same reasons that people like me sometimes buys and reads the same book in both its original and translated version).
G-collections has a section for english bishoujo games, but they haven’t put anything there yet, even through there is a few games that they could sell in that section…
