Well, I suppose being called a Psychopath's nickname is not so bad ^_^. "Borderlands" is about the only FPS I actually like, because it actually had an interesting story.
"Portal" is another one, if that counts. And "Half Life" (I could not care less about any "Half Life 3", though, I want a "Portal 3", but Value said that is not happening).
Well, they could make a short one about her life after her escape, and maybe trying to rescue/rebuilt Wheatley (since it's likely he crashed into the moon at some point, as orbit just does not work like that).
