Pokémon Legends: Z-A features a significant change in the gameplay: Pokémon will remain in the world even when players move away from them. This is a notable distinction from previous games, where pokémon would despawn after a certain distance or loading screen. This new mechanic will be a key focus for shiny hunters, as players will now have a greater chance of encountering rare specimens. The developers have confirmed that this feature will be available in the game, though further details will be released in a subsequent update.
