For this experiment I got my girlfriend who is by no means a gamer to play Team Fortress 2 and record her reactions. I had given her the basics of movement and controls earlier and what you are seeing is her first attempts since that.
It turned out to be really interesting to see a player who doesn't have the general gaming know how that we take for granted handle in a frantic and competitive environment.
She was a great sport and I thank her heaps for it! You can also see she is SUPER companionate. Go read my blog at http://www.simoncottee.com/
The video is a bit long. There may be a part 2 coming as I have heaps more footage.
