It s not a claim it s a fact it is most played Per person which the image shows Smash Bros was the previous most played game Per person according to the data on the Nintendo Channel You can go on the Nintendo Channel and search every single Wii game released I think you missed the Per person part not the total hours part If you missed older reports on Kotaku you can see one here before Monster Hunter Tri passed Super Smash Bros Brawl in the hours Per person category Quote from Kotaku article Where s all this from AKA an explanation of the above chart for stat junkies only In a move somewhat surprising for the generally secretive company Nintendo makes all of this data public Any Wii owner can download the Nintendo Channel to their Wii and begin browsing for games Any game that has been played enough times has usage stats listed for it contributed by anyone who chose to share their data with the channel Does that help
