not really an answer to your question, but i like in Milfylicious how you can choose the outfit the LI's wear in your upcoming encounter. So if leather over fishnet stockings is your thing and such, havent the agency to choose for the character rather than a character that specifically only wears one style is a nice touch.
I try to mix up the outfits in my VN, but sometimes you need to go back to a few of the same ones. It is fun looking for new outfits to put the girls in but the guy's clothing doesn't change a lot since I have a harder time finding ones I like.
I dont think the girls in Nympho Tamer ever wear the same thing twice! MC never changes his clothes though and does the thing where hi dick just emerges from his pants (way lower than his zipper too, its hilarious)
As a game designer myself, I've sacrificed many a person who suggested wasting system resources like that to the company brontosaurus. Money,money,money!
