An example of creative promotion; Prince of Persia Penny Arcade Story trailer

A couple of years ago I saw this promotion video for the back then new entry into the Prince of Persia series, simply called Prince of Persia (4) (http://www.gametrailers.com/video/exclusive-penny-prince-of/43932).

I really liked the style of this video (done by the creators of Penny Arcade) and it sucked me in, making me quite excited for this new game.

Technically it isn't exactly an animation. It's a very nice decorated slideshow, but it does have that animation flair and it is a nice way to explain the backstory of the game. Also using a different style really complemented the game it was based on, which also had a unique visual style.
