I'm a bit disappointed that you failed to mention that F2 is one of the very few games with its special Sex Proficiency Stat influenced by Charisma, Stamina and certain perks. The stat level determines your Chosen One's success in, uhm, let's call them special encounters. You can even sire a real heir to the throne! In a way, at least, one mini-quest lets the player woe the daughter of a powerful mobster and the game ending reveals that their kid takes over an entire gangster city. Talk about special achievements hehe
