It gets REALLY annoying when you get beat by the same opponent over and over again for 45 min. Other than that the facial expressions when they are hit (in Dan and Fei Long's case, there specials) are priceless.
Final Fantasy XI, Left 4 Dead, Quake Wars: Enemy Territory, Condemned 2: Bloodshot. Too many things going on at once. (IMG:[invalid] style_emoticons/default/sad.gif)
