Ah, but we are using different standards of what is and isn't a "defining" character. I'm using purely physical traits - I don't know or care where most of the girls came from, meaning that I don't know about their personality at all. It's totally fluid, in my eyes. On the other hand, physical traits are obvious (you can SEE them), and I would think that no one here would want those to change from game to game.
Now, when I say "physical" traits, you may say that things like Big Boobs and Long Legs should be included. I suppose that, by definition, yes they could; but I claim that with the caliber of girl that is included here traits like these are simply too universal to be "essential". You can argue that point, but it's basically an opinion call. On the other hand, there are a couple traits like One Eye (and, maybe, Tsundere and Yandere, since I'm not exactly sure what those do) that should be included; I had One Eye noted but Doc must feel otherwise, because he does not.
The whole point of the list is that it is arbitrary - I don't expect everyone to agree on it, but I maintain that an defensible argument can and should be made to keep the list as small as possible. Isn't that the point of this whole deal? If the list were too long, then this whole subject is basically moot. Personally, I feel that even 15 starting traits is too much - I'd prefer, say, eight or even six. My view on traits is that they should be special; some traits should be virtually unique, and even the more 'common' ones shouldn't be given to every girl. Of course, some traits don't apply under that assumption - MILF, the addictions, etc. - but as far as the fetish things go those should be rare enough that a player has to choose which ones they include in a brothel. You shouldn't have one girl that's able to service 80 fetishes; you shouldn't even have a brothel that can do that.
