Some of YouTube's top trending videos last week came out of the big E3 expo in Los Angeles, where video game industry leaders debut the latest titles and technologies. Below we ranked the most-viewed videos from the Gaming category that were uploaded within the past seven days, and, as you can see, they are mostly previews from E3.

The two games that drew the most buzz seem to be Assasin's Creed and Battlefield 3, both of which had multiple videos in the top 10. We've only included one video for each game below, however.

(Ranked as of Monday morning. May take a moment to load in full.)

If you have a favorite trailer, you can vote for it now in our Game Trailer Challenge.
