To the people thinking the guy in OP dodged a loaded question... let me ask you, are there any female characters you'd fancy being in a relationship with? I don't mean a one night stand, I mean someone you could spend a sizable portion of your time with and think you'd enjoy their company... I can't think of too many personally.
Well, here, let me go ahead and ask you a precursor to that question.
Is there enough appearances and dialogue that a female character has so that I can determine if I would "fancy" being in a relationship with?
Not much. If at all. Why? Because video games are incredibly shallow experiences of characters or people (if you think of them as that). 99% of the games out there are 2-12 hour experiences in which you MIGHT have 20 minutes of dialogue with 1 particular character, and its not like you have control of what kind of questions or dialogue you can have with them because thats not the point to a video game, folks. A game has a win condition that you're driving towards, and dialogue and character development is very much a really shallow afterthought on the whole experience itself.
But since you asked, I'm going to answer anyway just to prove a point and how ridiculous this whole thought experiment is.
I'm going to go ahead and briefly explain what I liked or disliked about all P3 and P4 female characters and if I would date them or not. Keep in mind that not everyone likes playing a 50+ hour RPG. A disclaimer here, I've maxed their social links. So, yes, I've exhausted their dialogues with the main character.
P3:
Yukari: Kind of stuck up bitch, and confrontational in pretty much the worst of all ways with the rest of characters. She is like that person you know that goes to your party and bums everyone out when they just want to have a few laughs and have a good time. No, I wouldn't "fancy" her.
Mitsuru: Leader, Student body president, Responsible, Strong convictions, Smart. Very much out of touch with people below her, but thru dialogue you learn about her flaws and she ends up becoming a more down to earth person when you max her social link. Absolutely would "fancy" her.
Fuuka: Severely lacking in the aspect of courage and confidence. Its just not attractive to anyone unless you like "fixing" people when you date them. Wouldn't "fancy" her.
Aigis: Robot. Touched her circuit. Wouldn't "fancy" her.
P4:
Chie: I know I'm going to get flack from the Chie lovers, but I don't find her attractive in any way. The only thing I got from here was that she loves meat and kung fu movies. Gets too embarrassed, and I don't find that attractive. Shitty cook. Wouldn't.
Yukiko: Kind of a dork with her laughing and jokes. Too timid for my tastes. Shitty cook. Wouldn't.
Rise: Idol. Not actually an airhead. Bold personality. Shitty cook. Not sure if I would.
Naoto: Smart. Has an identity crisis. Has a sweet side to her. Probably a shitty cook, too. Not sure if I would.
Marie: Not going to spoil her story. She is the Bamboo forest. Tsundere and naive, but has some really cute moments. Would.
So, in conclusion, if you look closely at what I said I would or wouldn't "fancy". You'll notice that somehow I went for the characters that had more sex appeal. And I didn't to the ones that are butterfaces by comparison. I just wanted to point out that I have the upmost respect for Shigenori Soejima's work in the Persona series. All the characters based on their physical appearances have their charms in their own ways, and to each their own.
