What is your favorite video game trailer/s?

Diablo II
 

The original Brawl trailer told me that the game would be awesome before it even came out. So did the site.

I remember the first time I saw this my jaw was on the ground,I must have watched it 20 times in a row.It was the most amazing thing I had ever seen,lol.
 
 

I don't really have a favorite. A couple of those celebrity endorsed WoW ones were kind of funny. 
 
I'll tell you what one I hated though. The Gear of War/Mad World one. It got played in the previews at the cinemas so many bloody times for so long I justed wanted to punch the old lady and her grand children in the row infront of me. Everytime you went to the movies around that time you could gaurantee it would be on it was infuriating.

One of my favorites was  the WoW office space commercial. Also the trailer without voice-overs for Jet Force Gemini used to be one of my favorites.

I loved this one, I don't have a favorite though. I also love the Meet the ___ TF2 vids.
 

ubisoft generally make good trailers, i remember  prince of persia having a few good ones, to bad there was no substance behind it all
