Capcom will let you know. This number includes digital sales and Monster Hunter World: Iceborne Master Edition. Last year, World already became Capcom’s best-selling game ever, and that hasn’t changed.
Monster Hunter World was released on Xbox One and PlayStation 4 in early 2018 and also came out on Steam later that year. Iceborne expansion was released in 2019.
The publisher is pleased with the success: “Capcom has been able to make the Monster Hunter series known worldwide with World, thanks in part to the simultaneous global launch and international promotional activities.”
