3. Star Wars: The Old Republic - Knights Of The Fallen Empire
Even if you're not a big fan of MMO's, Bioware's CGI trailers for their epic 'The Old Republic' never fail to impress, and the one for the free expansion (yes, free) Knights of the Fallen Empire was particularly epic. The trailer sets up the premise of the expansion perfectly - focussing on the bond between two brothers and the rift that comes between them. It's Bioware's famous story telling at its finest, so it's definitely not one you want to miss.
