I found Tali from the Mass Effect series attractive. I think it was just the air of mystery around her looks. Also, her nervousness around Sheperd when he expresses interest in her, I find really adorable. X-)
Nothing on my end. Played the 360 version and also didn't mess with any of the sensitivity options. Found everything to be on target. To be fair though, Starbreeze always had a weird, yet oddly satisfying way of handling shooters.
