All "Overview" Posts Updated With E3 Videos

You can now go into the "Overview" posts from the Ubisoft, Sony, or Nintendo conferences and simply click on the name of the game listed to view its trailer/footage on YouTube.  Some of the games didn't have true cinematic trailers, but rather gameplay trailers (such as Far Cry 3), so the assortment of videos are quite varied.  I felt the urge to include gameplay demos for some of the games; they are definitely worth checking out.
