Christina from Bioware here for a quick update. I have some random E3 photos too! Sorry iPhoto photos not the most awesome quality.
So today my first day of demoing Mass Effect 2 behind closed doors with Casey Hudson. E3 didn't open until noon, but I got there at 9am to double check that everything was working well. It was! EA set up the booth really nicely, great hardware and a beautiful booth.
Some nice Mass Effect 2 signage at E3 as well. There's more than this but this is the only one I got a photo fo.
I practiced the demo again a few times and before I knew it I was giving live demos. Everything went really smooth, and people seemed to enjoy the demo, what else can you really ask for? There is coverage of the demo in a variety of places. You can bug Brad Nicholson if you want a review of the demo, he saw it!
Finally, here's a photo from kare3oke of me hugging Jim Sterling mainly because it's ironic!
