When we were at Bigbig Studios working on our Vita title Little Deviants, he was in fairly frequent contact with the studio. We would do numerous builds and demos for different stages of development and later more so for the various events (including the original NGP reveal).
He loved the deformable environment demo and basically wanted the entire game to be that, not caring about different levels, other game mechanics or such things. "I just want a playground, build me a playground to have fun!" was all he ever used to say. He obviously knew we needed to make a game with more to it than a simple level where you play about, but that's all he cared about
He's a genuinely really nice guy and incredibly friendly and surprisingly open for someone of such authority.
