SIE is a great character. She's a very direct approach type of woman (regarding sex or combat) and her being so flirtatious is actually really ****ing funny. It's like it moves past cringe-inducing pandering to 14 year old boys and into SIE being that way, as a human being.
But on the other hand, the other three love interests are different, in a positive way. They aren't defined by their sexuality or your ability to have sex with them, unlike love interests in certain other games. It's perfectly plausible that you could play through the entire game without realizing that Mina/Madison/Scarlet were love interests. While it's certainly possible that you could miss that SIE is (some dude didn't get what Confirmed Bachelor meant in Fallout New Vegas), she is not on the same level at all.
SIE has other character traits, of course. She's an "aggressive" character, she likes blowing things up. She lives life to the fullest, I guess you might describe it, and her sexuality is just one (loud) part of that personality.
The thing is, though, I'm not sure that I can think of much else of her character. I probably wouldn't accept that alone as an excuse, but then there's the ending to her love interest arc, and it really pays the bill. Just as every previous interaction with you on the subject of sex has been dominated by her (if you're actually romancing her, you have to say "thanks, but no thanks" to pretty much every comment she makes) and she dominates the sex act itself when she basically rapes you (though you can avoid this fate by choosing the other option, so it's not "really" rape).
I don't know, this is kinda rambling. Thoughts?
