It wasn't as nice as on the 3DS to get the numbers, but at least the Wii U shows the total time if you click on the title of the game. However I wrote down all games with more than 10 hours playtime to compare them and find out which were the most played ones. It was too much work to only show the top 5, so I show all 50 games, with more than 10 hours.
