I have no idea how reliable these numbers are btw, but it probably gives at the very least a good sense as to what is going on. And no I am not in Japan, but I'll try to watch it at some point.
Based on the couple gigantic and enlightening pieces by Tim Rogers on that... thing... I can't decide if it's very right choice or a very wrong one. Very right if you want to reward the excellence in Kafkaesque, soul crushing, goal-less, money grabbing scheme. Very wrong if you want to reward something that has some ethics and represents a positive evolution for the game industry (but then who would you give that award to?).
It would be interesting to have that number for games that are campaign heavy with a lighter/gimmicky multi-player mode. Like, say, Uncharted 2.
