There's an interesting thread talking about male love interests in APs. And it got me thinking--what do you want to see in a love interest in general?
Personally, I play lots of different characters of differing genders and sexualities, so for me, it's not necessarily the stock "hot chick" or anything like that. I prefer a love interest who is bright and active. It's okay if the love interest requires rescuing, falls prey to villains, or is super-competent and that sort of thing doesn't happen. I like them imaginative and energetic.
Hard to say. The only characters I've gotten to play long enough for anything like that to form were completely disinterested in it. My players seems to just like NPCs that I've acted well, and that contribute in some way to the group dynamic. If they're just a fly on the wall, there's not much reaso nto keep them around, or ask more questions.
I'd like to see a female for my new rogue, Victor, who is intuitive, but gets herself into trouble, can fight her way out of a situation, but isn't offended by being "saved". Is "cute" but not beautiful. And sees some good quality in me that I don't see in myself that keeps her coming back even when I mess things up like I do.
Oh, and she should be a little bi-curious. And it would be hilarious if she kind of developed a crush on a very smart, sassy, and tough woman who made me have to work my tail off to keep my girl from dumping me for good.
