Modern Warfare 2 (the first one). When you're climbing the ice wall and you fall and get caught, the level of detail on the face was astounding to kid me. It was like watching something in real life to me.
Probably helped that it was off of my sister's high def TV.
One of my favorite examples of people getting things embarrassingly wrong is the "Taiwan is not part of China" crowd. Both sides historically disagree with this. Taiwan being a part of China is not some point that has been in dispute until very recently.
The disagreement has historically been over which is the "rightful government". Sure sentiments in Taiwan have been changing but even this year there was a former Taiwanese president saying this explicitly

Any of the dumbass Americans who proudly declare "Taiwan is not and never has been a part of China" can be easily dismissed.
