I would be interested en GH3: Legends of rock numbers (I am outside for a few months and I coulnd't bring my Wii as I have no TV here)... because if it was for me (and my friends in co-op), the average playtime would be @300h/person
Anyway, 73h per smash bros seems a bit low... but I suppose not everyone plays as much as me xD
And I would also be interested in Mario Galaxy numbers... 20 hours seems TOO low...
By the way, interesting numbers... I didn't know you could search for that kind of data... I just use my Wii for playing and nothing more
