Pokemon Legends: Arceus is completely different from its predecessors in a number of different ways. As well as being an open-world title, the game also allows players to catch certain Pokemon without having to engage them in battle and crafting now plays a much larger role in the overall experience than ever before. Perhaps the biggest change, however, comes in the structure of the game's main story, which replaces gym battles and badges with a series of missions through which players must prove their worth.
