Zia, from the Bastion. The girl could use some company, in this situation, I guess I could be the Kid. And then Rucks would get to narrate it all...
Generic Princess from Medieval 2: Total War. Getting into the royal family might be nice, but god forbid that my player decides to send me on a suicide run...
Jaina from Warcraft. She's smart and throws fireballs around. *Shrug* I mean, if she's not busy being sad over Arthas... Hey, my avatar!
Haruhi Suzamiya's randomness might actually get me to do things besides waste my time on the internet.
Konata from Lucky Star: From the few episodes I've watched and the short youtube clips, Konata's otaku lifestyle would compliment my own.
And who can forget most of the cast of Katawa Shoujo?
Possibly more to come later, but I'm not that big on relationships at this point in my life... I mean, I got college coming up to seperate us, and I've never really had one before (disregarding one strange issue involving two girls liking me at the same time and me being indecisive, and then chosing one and recieving no response from that one, and the other going further...nyet.). So, as a purely hypothetical situation, those would be my current choices.
