Correct me if I'm wrong, but, aren't themes usually planned by developers? If they're not setting out to make those games sexist in the first place, then there is no 'theme' only a perceived, and very misguided, notion.
Wanting a sexist 'theme' to exist in something isn't the same as it actually existing. The damsel in distress plot isn't some age old plan to display women as the 'weaker sex', it's cliche, but it's not part of some plot of the "patriarchy".
