Surprised that an Expansion for MHW boosted Ps4 sales.
MHW did okay, on COMG it did pretty bad, but in Japan as a whole it did okay.
Well the retail version of Iceborne is the Original version + the expansion.
So everyone who already had the original MHW would probably just buy the expansion, which is cheaper, and digital only.
In other words, Iceborne probably sold a lot more digitally. Even last time, the digital version was over 50% on opening week in Japan. But that time it was mainly due to the retail version being sold out. This time there's a strong incentive for people who already own MHW to get the expansion digitally.
