Here's the map of Tokyo Game Show 2007. As you can see, it is quite an elaborate setup -- as always, there's a food court, dressing rooms for cosplayers, a kids' corner with its very own event stage, etc. I'm surprised how large the Level 5 booth is. Even though they're shuffled off to the back of the show next to such untouchables as Microsoft, they've got a huge presence. They're on their way to becoming a major publisher, I'd wager.
Also, check out the video games history area! That should be awesome.
