Monster Hunter 3 now has highest Wii play time on US Nintendo Channel!

[Hanzor]

I helped just a little bit with my miserable 850 hrs. (According to Nintendo Channel) or 750 hrs (According to In-game)

But since i use MHT online as my only way to communicate with certain friend i would say: 600hr of actual gameplay and 250 hrs of idling/chatting since release day.
