12. World Of Warcraft
https://www.youtube.com/watch?v=dYK_Gqyf48Y Say what you want about Blizzard - they know how to build hype. This first trailer for World of Warcraft was the first time we saw some of the most iconic, memorable locations in video game history, as well as many of the races that millions would devote much of their lives to. Best of all, is Jason Haye's incredible scoring, combined with the exciting action depicted in beautiful CGI. The trailer showed off a world that was familiar to some, excitingly new to others. Either way, the end result was unlike anything seen before.
