Well, I’ll quote what he said there and then question it:
"A number of people have asked us about why there are almost no playable demos for bishoujo games. A lot of it has to do with differences in video game culture between the U.S. and Japan – simply put, Japanese game companies almost never make them, so it’s not possible for us to translate demos and make them available for download"
This sounds like a lie, or close to it, since there is playable demos for some games; there is the Brave Soul playable demo (and from what Unicorn has said, there may be one more BS demo). and futhermore, Unicorn has more or less confirmed that a couple of other playable demos made by Crowd. So instead of saying that “We can’t put out playable demos”, why not say that “There is some demos out there, but we’re short on time and resources to translate and redo them in english, and to do that would delay our work on our current games too, and you don’t want that, right?”… or something like that, anyway?
