The VGC Foundation's plan for Anime Expo is quite impressive, if it looks as good as its model video it put up online. The History of Video Gaming Exhibit will be a massive area covering gaming since the mid 1970's through multiple consoles. There's even going to be a “One Hit Wonders” section of some of less-off consoles that never quite made it. You'll be able to play them all. It's not going to be an exhibit with everything behind glass.
Let's hope they can pull it off. A friend said that the same group did well at Comikaze last year, so let's hope they can one-up themselves for AX.
