All children's software today seems to be designed for the preschool through kindergarten age group. The rest is for adults. Seastalker, like The Hardy Boys, is for ages 8-14, and even 10 years later it remains about the only game specially geared towards them. Since the purpose of children's software is always to educate as well as entertain, an all-text adventure seems especially appropriate. It's only a pity that there aren't more.
