Favourite video game trailers?

Sorry if im spamming the misc. forums with all these topics..anyway favourite game trailers. Here are a few of mine. Wouldn't classify some of these as actual trailers so please dont flame me about them not being trailers. Would add the infamy trailer but you can view it in the previews section.
All amazing trailers,tried to write a countdown of my favourite to my least but i couldn't, just couldn't, they're all amazing trailers. Edit:I will continue to update this as more and more trailers continue to come out so stay tuned.

Please don't hurt me for showing this, don't hate Halo it ain't too bad.

I would put BF:BC's Bad world here but since its already posted up, I got more.
