I wouldn't say it has battlefuck mechanisms, as that there is not really "sex" during the fights as far as I can remember, it's more about dominating/nude/humiliation during the fight and sexual domination as a prize. What I like about these games that there is a bit more story and body to it, which is more common in sandbox games, while the ones mentioned in the list are often just random matches. Kinky fight club and heroine rumble do have great mechanics and a small bit of story, but I would really like to see that translated in a freedom-sandbox with DAZ graphics, a man can only dream.
