I find good the idea, basically it gives a kind of "social" sex education (I mean not the biological process, but the acceptable behaviour/attitudes), it helps the prevention of becoming the victims of a not only illegal, but unequal and abusing relationship, and it might be able to reach enough well the group of age in focus, because the program developers chose the form of a video game. However I'm not sure that it will be too efficient, because the sexual abuse of children, the paedophilia and the criminal cases what are related to it, seem to me a more complicated issue, but the education, telling about the dangers is important anyway. Even if it's probable that who would need the most this kind of education will miss it the most too. If there is only one or a few children who avoid this situation by its help, it's worthy already.
But it's shocking a bit, I have to admit sincerely, because I still think that giving a similar education about norms of the acceptable forms of sexual life/attitudes would be mainly the task of the family, and the responsibility of parents, and its lack won't be probably compensated by video games. I know, I know, it's better than nothing, and lately the young people (pre-teens too) just get and reach too easily too many kinds of (confusing) information about sex, so they can become victims even if their parents act as responsibly as they can. But it sounds a bit as we would "dehumanize" a process what is firmly related to a theme what is one of the most human and intimate ones. Well, I'm surely naive and old-fashioned... so many technocrats lately. Anyway, welcome in the XXIth century.
