The Pokemon Company clarified that Pokemon Legend: Arceus Not an open world game, as many people assume based on the original description of the game and watching the trailer.
Based on the clarification, it looks like the game will be similar to Monster Hunter, because instead of running idly around the world, the main village is used as a base of operations. Here, the player will choose a mission before setting off to the open area.
Although the Pokemon Company did not specifically mention Monster Hunter, it sounds similar to how expedition works.
This is the complete statement Send to Kotaku:
In Pokemon Legends: Arceus, Jubilife Village will serve as the base for investigation missions. After receiving a task or request and preparing for the next hike, the player will set off from the village to study one of the open areas in the Hisui area. After completing the investigation, the player needs to return again to prepare for the next mission. We look forward to sharing more information about exploring the Hisui area soon.
In the old Shenao region, in Pokemon Legends: Arceus, you will try to complete the first Pokedex ever.
By choosing Rowlet, Cyndaquil or Oshawott as the starter Pokémon, you will work with a “mysterious professor” who travels the world.
The gameplay allows you to observe Pokemon to understand their behavior, then carefully sneak in and aim your Poke Ball. You can also make your ally Pokemon fight against the wild Pokemon you wish to capture. Just throw the pokeball holding the ally Pokémon to the wild Pokémon, and you can seamlessly enter the battle and command your Pokémon.
Arceas is a special kind of Pokemon that clearly shaped the world and is related to your story.
