Pokémon Legends: Z-A takes on average about 22 to 30 hours to complete if you focus mainly on the main story and some side quests. This playtime estimate includes reaching the credits with a decent amount of Pokédex completion and side quest involvement, similar to previous titles like Pokémon Legends: Arceus. If you rush solely through the main story, the time can be cut to roughly 15 to 20 hours. For completionists aiming to finish all side quests, fill the entire Pokédex, and unlock all Mega Evolutions, the total playtime can extend up to 70 to 80 hours or more. The game map is relatively small, consisting of one large city, Lumiose City, which can be traversed fully in about 6 to 7 minutes of real-time running, but offers vertical layers and some exploration elements to extend gameplay. The length reflects a balance of story-driven gameplay and collecting activities typical in Pokémon spinoffs.

Thus, how long Pokémon Legends: Z-A lasts depends heavily on your style—whether you are focusing on story progression or full completionist objectives.
