I believe the Monster Hunter World team has been working on this game since the release of Iceborne in 2019, which means they'll have had almost six years to develop it by the time it's out in 2025.

But while Rise is the most recent Monster Hunter (and a very good game!), it's clear that Monster Hunter Wilds is a direct successor to 2018’s World rather than 2021’s Rise.

Monster Hunter: World, released in 2018, did away with the segmented maps that players were used to seeing in the series, instead allowing them to roam about a single stage without loading times.
