Update, 10/8/2021, 6:00 p.m. ET: The Pokémon Company has sent Kotaku a statement confirming the Monster Hunter-esque structure of Pokémon Legends: Arceus.
In Pokémon Legends: Arceus, Jubilife Village will serve as the base for surveying missions. After receiving an assignment or a request and preparing for their next excursion, players will set out from the village to study one of the various open areas of the Hisui region. After they finish the survey work, players will need to return once more to prepare for their next task. We look forward to sharing more information about exploring the Hisui region soon.
