In asking PR rep Jimmy Soga, he informed me that it was the decision of Marvelous to yank the game from the show. Why? Well, they felt it wasn't a strong enough build to show the public. I asked if it was perhaps a problem of the game crashing or it being that the section quarantined for the press at E3 was rather glitchy, but he had no other information for me other than I would not be able to play it.
Stay tuned for impressions from the games that are at the show.
