Maybe it is just me, but I got the feeling that the other story arcs are lacking in comparison to my most "successful" character created who went through lots of - very well written and entertaining - sex. Just my two cents - I could be wrong, but this is my impression after trying out different characters.
I'd say that the most significant skills, the ones that
actually determine what Claire can do with her life, are Discipline and Stability. They affect how easily she's roped into crazy hijinks, how she performs at school, what college (if any) she goes to, and all of those things make up a pretty large part of the game so far. A close second would be the "sexuality pair" of Risky and Easy, which heavily affects the kinds of sexual adventures she can get involved in.
Attractiveness itself doesn't come up as often as you might think. It's pretty much reserved for checking to see how successful she'll be in a role that requires traditional beauty, like when she tries to pursue a modeling career, when she's going for hookups in high school, trying to be a college cheerleader, and the like. That covers a few scenes, but there are lot that aren't heavily impacted by attractiveness at all.
The other thing to keep in mind is that
this is a porn game. Yes, it aims to be reasonably internally consistent and is fairly high quality, but make no mistake - the point of this is to offer a titillating adventure to the player, and the sections that have sex are probably going to be the ones given the most attention. In these kinds of games, the "not having sex" option is usually meant as an out for a player who doesn't think their character would do that sort of thing or who doesn't want to experience a particular scene. Games that try to offer equivalent depth of experiences to non-erotic paths in erotic games tend to get dinged for the "pick between story or sex" problem, as many of us are here for story
and sex.
Plus I would like to see the choices about the things our MC has learned about her sexuality play out more (more obvious, maybe) after these choices, I'm talking about the list with exhibitionism, bondage and so on. It is a great list with promising fetishes that I don't see played out in the following scenes. Is that WIP or am I just too stupid to notice these details?
I haven't looked deeply into the latest version for sexual kinks, but last time I went through there were a few checks for them and they were pretty much exclusively flavor variations on existing scenes. When she's doing the gap year in Africa, for example, she gets a remark about being turned on by the local fellow having sex with her unprotected if she has the Breeding kink.
