Go watch Dr Horrible's Sing Along Blog. She's pretty much a minor internet celebrity.
Edit: Waggle confirmed! Is it just me or did they just screw over Tony Hawk big time?
Two timed-exclusive Call of Duty map packs for 360. MEGATON!
EDIT: First Final Fantasy came out in 1987, the only thing that has changed for FF XIII is the graphics. Go JRPGs...
Less than an hour to go!
You should be able to get the live stream from http://e3insider.com/ or IGN but IGN wants a custom Firefox plugin. It seems to work pretty well, though.
You should have posted the one with Ms. Wolff, that got some real traction in the AP forum.
The EVE Online trailers have also always been really great.
EDIT: Yay, we're avatar buddies!
That's weird, maybe adblock is protecting me or something, I did get some malware-free sprays there a while back. I'm sure there are other friendlier sites, that's just the one I used a while back, sorry about that.
I really like the Dead Space "Lullaby" trailer as well, really well done with the music and static cutouts.
Another one that comes to mind is Half-Life 2: Episode 2 teaser trailer with the wonderful voiceover.
I haven't really imported anything into HL2, but I did import some sprays into TF2 and I can tell you that the Source engine is very fickle about what it accepts and what it doesn't. Check out fpsbanana for lots of tutorials and whatnot, I think they have HL2 stuff as well.
