Nintendo's RPG-extension of the popular Pokémon brand continues with Explorers of Sky, a title in which gamers once again take on the role of a Pokémon creature embarking on an epic journey to save the world from complete annihilation. Players begin by taking a personality test, with the answers they provide determining which of the 19 playable Pokémon they control. They then head off for an extended series of the dungeon-crawling adventures, purchasing new items and supplies in Treasure Town, training for battle, interacting with more than 490 different Pokémon characters, and unraveling more of the Pokémon Mystery Dungeon storyline in a series of "Special Episodes." Multiplayer fans can share items or join a friend for local co-op adventures, or they can use Nintendo's Wi-Fi Connection to access special missions.
