The Kingdom Hearts series games contain elements from both action and role-playing games. The games are driven by a linear progression to the next story event, usually told in the form of a cut scene, though there are numerous side quests available that provide bonus benefits to the characters. The player is primarily in control of the principal protagonist of the series, Sora. Sora is usually accompanied by Donald Duck and Goofy, who are non-playable characters that aid Sora in battle. The games featured real-time combat that incorporates physical attacks, magic, and summonings; though each game handled battles differently. Like many traditional role-playing games, Kingdom Hearts features an experience point system which determines character development. As enemies are defeated, the player gains experience which culminate in a "level-up", where the characters grow stronger and gain access to new abilities.
Universe of Kingdom Hearts
The universe of Kingdom Hearts is a collection of various levels, referred to as "worlds", that the player progresses through. Each world varies in appearance and setting, depending on the Disney world that it is based on. The graphics of the world and characters were meant to resemble the artwork style of the environments and characters from their respective Disney film. Worlds are made up of interconnected field maps where battles and events take place. Each world is disconnected from the others and exists separately. Most characters in the worlds are unaware of the existence of the other worlds, but some notable ones are aware.Players travel from one world to another via a Gummi Ship.
