I come off as harsh on DMD, but that's because I feel like it has a ton of potential that is wasted because the writer seemingly doesn't understand women well enough to write believable characters. More than that, the "be a gentleman" trope kinda bugs me, because, outside of My Sweet Neighbors, every time I've "been a gentleman" in a game it just meant "keep trying to be creepier and creepier while she gets more and more used to it". MSN is the first game where I've felt like the options were leading to a mature and well developed relationship.
I'd even argue that the habit of making the MC a sex date rapist is one of the many reasons I feel like there needs to be more quality games, why I'm writing one. The content will still include themes of incest, light corruption, harem options, etc, but the characters will be well written. You'll care about what happens to them and why. You will have an emotional investment in your decisions so that when you're deciding to peek or not to peek it isn't about getting to the sex, its about developing the relationship in the way you want.
I have dual MCs the respective love interests of the main story line. Throughout the first bit of the game you'll have a few options and depending on what points you accrue or don't accrue the story will evolve. If with the female character you do the bold thing twice, there's a masturbation fantasy scene in which she touches herself while imagining its being done by the male MC. If you don't take every bold choice leading to that she goes to bed frustrated. When she wakes up in the morning we learn so much more about her character if she didn't masturbate than if she did. That doesn't make the decision to masturbate wrong, it just means that as the story goes on each branch will have its own rewards. Following the most sexual branch may lead to a less sexual ending, following the least sexual branch may lead to the MCs simply seeing other people, of which there are a few.
I think these games have far greater potential for greatness and emotional investment than most of the popular titles do. I like Dreams of Desire and Dating my Daughter, but I think both could be better in many ways. In a way its the difference, to me, between the drug store pulp erotica, and the award winning drama. Sometimes a little pulp erotica is fine, but you'll always get more from the award winning drama.
