 Completing the main storyline opens up other features in the games; this is primarily done by allowing passage into otherwise inaccessible places.Afterward, the game remains virtually open-ended, with the ultimate goal of the player being to obtain at least one member of each of the different species of Pokémon, thus completing the Pokédex.The number of Pokémon increases with each game generation, starting from 151 in the first generation to 890 as of "Sword" and "Shield".
