There's like zero reason it'd be anything other than Monster Hunter World.
The series just absolutely exploded in the west. Hell, Steamspy has it at over 2 million copies sold in just 3-4 days on PC.
The game has demolished every single Monster Hunter before and did so at the same time making the jump from portable to home console/PC and leaving behind its prime fanbase as a Japan-focused Nintendo handheld title. It blows everything on the list away because absolutely nobody thought MHW would do anywhere close to what it has done.
