For comparison, the two versions of Yo-kai Watch 2 sold 1,281,096 units at launch over a four day period. The original Yo-kai Watch which came out on July 11, 2013 sold 52,901 units over a four day period. Level-5’s series keeps growing at an explosive rate, which probably explains why they’re focusing more on Yo-kai Watch than Inazuma Eleven now.
