I went and saw it this weekend, and I had totally forgotten that we had a thread about it on this very site! But there it was...PSI and IV both featured. I was pleased to see Shadow of the Colossus and Okami also be represented on the Playstation 2, and some other very worthy games on other systems, like Portal. No EarthBound, though.
But still, pretty awesome. Go see the exhibit if you get the chance, it's pretty neat!
