[b]I use a controller, because the game was DESIGNED to be played with a controller, and there is no net benefit to playing it with mouse and keyboard.[/b] What you gain in aiming accuracy from using a mouse, you lose in freedom of movement by using key strokes...and that movement is just as important (if not moreso) to success in this game as your ability to shoot accurately. As for the guy you ran into? Arrogance, Ignorance, and insecurity all riding in the same car makes for a **special** kind of pain for everyone else. Don't waste your time worrying about him, and I hope you didn't waste any trying to educate him.
