You surprised by this list or was it about what you expected? Anything you expected to be on here?

*if anything is inaccurate that you can tell, please tell me. :) and  it HAS to be from the E3 event, remember that*

Oh great, the Super Mario Galaxy 2 trailer got many views
Otherwise, extremely predictable top 5

I'm shocked nothing older than the 7th gen is on there, that's for sure.

youtube was made in 2005 so its quite understandable

Lol, I knew that. I've gotten so used to it just being there all the time it feels as though it has been around since the 90's...

I think a lot of these are going to be replaced after this e3. With all the hype surrounding the new console launches I think we will see multiple videos up there. the reason Nintendo didn't have one up their for their launch was because they had a pretty lackluster e3 (to be fair they all did). I think this e3 everyone has to bring their big guns to the table which should lead to some awesome videos.

i'm not so surprised about these games, they all did well in the end. I look forward to E3, hopefully 2 new systems means a exciting E3
