That's one of the reasons I really like Acerola games. Solid, funny writing, plentiful (and decensored with Kagura) sex scenes that are an integral part of story/gameplay (unlike many games where the smut is just bolted on over standard JRPG fare), good art, and decently long.
A few people say it's same-y, which is true, but they're generally different enough in plot, and have their mechanics mixed-up and built on with each iteration (especially their NTR line) to make each new one interesting to play.
Except Phantom Thief Celianna. That game was awful.
