Nintendo's entry into the mobile market doesn't appear to be gaining momentum, as Dr Mario World has only generated $100,000 in its first three days.
That's according to data from Sensor Tower, which also reports the game has racked up two million installs so far.
The company recognised that Dr Mario is not as high profile a franchise as Super Mario, Fire Emblem and Animal Crossing -- all of which have received mobile releases -- and was not marketed as heavily as previous titles. Nonetheless, it makes for disappointing figures.
