people will read the description when the description is available to be read.
I dont know if you noticed, but when you embed a video, the description doesn't show up.
and I'm sure every single person who came to this thread only clicked to play the video, rather than take the extra time to go to the actual youtube page.
This primarily being a GAMING site, its easy to understand how people would assume A.D. to be a video game.
You have to admit, it really looks like one.
