This is seriously odd...I am getting motion sickness playing HL2. It's never happened in any game before -- after about 30 minutes of play, I felt dizzy and nauseous. I have played through tons of FPS games, but this is the first time I've ever experienced something so palpable as a result. Maybe I am losing my mind, or I'm about to start screaming out "Altobello!" while having a diabetic stroke, but damn!
