E is for Eloquence

Which I seem to have lost at the moment! I am trying to write this essay on the narrative potential of video games, and although the words are in my head, they are not coming out right onto the paper!!

AAARRRGGGHHHH!!!!!

I can chatter about it, I can think about it, but when it comes to writing it, I seem to have lost all ability to construct a cohesive argument!
