Maybe this is kind of Cliche, but Aeris. Shes incredibly kind and compassionate, was a really well built character, and outside of all the crazy stuff she has going on, she is quite down to earth.
And no, this isn't a big interest of mine. I'm not obsessed with the character. This is a silly, hypothetical, unrealistic internet conversation that kills some time and makes for a few laughs. Also, asking for female characters in games which have traits you are interested in is far too unwieldy of a question to ask. Some people think this is a weird question, but really, its only weird if you force it to be. No one actually plans on dating any of these characters, and I bet more then one of us here have named a character which reminds us of a former, or present, flame.
