I'm not a big fan of the "bad guys only" story line, nor the sexual advances. I don't mind a romance option, but I've got to consider not letting my kids play if it doesn't clean up a fair bit. Maybe a preference switch?
The game is not aimed at children, but is explicitly adult-only (rated Mature 17+).
