Can only speak for me. She's not unattractive, but the Loli thing just doesn't appeal to me. While I find Kaylee one of the hottest around, and Amelia close behind.
I think said earlier in this thread that I am over the (sometimes) cute, bitchy, entitled, full of herself younger sister trope. They're often also blackmailing and rapey. I know that this is the wetdream for many players (especially if you add red hair, freckles & nerd), but it does nothing for me (happy to leave those for those that want them). Stephanie fits most of them including the blackmail and raping, and when she gets forced upon me, without being given a choice, it pisses me off even more.
To be brutally honest, if it wasn't for Kaylee & Amelie, I would have deleted it already. I can't stand Mia or Lauren either (for other reasons). But that's just me, everyone has different tastes.
